Slow Upload Speeds on Internet Port

Sun Aug 19, 2012 12:36 am

I have an RB1100AHx2. My speeds from ISP are 50meg up and 50 meg down. If I plug my laptop directly into my line from ISP I get advertised speeds. Plugging the same cable into my router gets me 50megs down and 25 megs up. I have messed with MTU settings with ISP as well as auto negotiate and no change. I have bandwidth set to unlimited. Any idea one what the issue may be?

Configuration and/or cabling issue.

P.S. and/or capacity (not)planning issue

Hi - I'd tend to agree with NetworkPro -- that being said:

MSS settings adjusted as well or only MTU on the Routerboard? When running via the routerboard - are you the only user connected during testing?

How are you running the tests -- proper iperf or similar I trust?

It has something to do with ethernetports. When i put a file on FTP server of Mikrotik I can down/uploadload it with a speed of 50/50Mbps. A PC behind the Mikrotik will not get this throughput. I tried several different PC's and tried different settings in MSS and MTU. Witch Cisco 800 series or direct PPPoE from PC I have no problems.

Configuration and/or cabling issue.
This is a less than helpful observation. What someone who has this issue on their router would like to see, is I have had the experience and it was fixed by making "this" configuration change. The poster stated he tested the cable so we can assume it is a configuration issue of some sort. The million dollar question since this has not been answered is what configuration and has this been fixed.

I have a similar issue with a RB2011 now running 5.21. I was only pulling 3-5 Mbps of 50 available. I had to change the lan speed on the port to manual 100 full duplex and it helped some. I'm now pulling 40 Mbps ish on the download but only about 25 on the upload. This is however, on a basic speedtest site and not on iperf.

I still have testing to do, but it does not seem that I have all the fine tuning that I need to get the throughput available. I have seen this on a couple different routers / RB versions and finaly got frustrated enough with it to come look on the boards. I'm hoping someone has posted somewhere with performance tuning recommendations? Anyone have any ideas?

Thanks - paul

I like short posts - easy to read.

RB is tuned out of the box.

Speedtest on a website rarely fills up providers' advertised speed.

Download many well seeded torrents and see amount on traffic on RB port.

p.s. port auto-negotiation issue is not "performance" or "tuning" issue - possibly the makers of the chips/devices on both ends did not have an interoperability lab. In the industry this issue is "owned" by whoever is setting up the connection. Congrats on making it work on 100 (or 1000?) full duplex.

Did anybody found a solution for this problem? I'm fighting with this issue since the first day I have MT router ( ROS 4.x) . I have multiple mipsbe routers and all of them shows same behaviour. The first version which shows significant improvements is ROS 6.0rc5.
I have 100/100Mbps dedicated ports on a Cisco switches in a DC. Without MT router 100/100 is not an issue to anywhere in EU, but with MT router local sites are running close to 100/100, but distant sites are running 100Mbps down /15Mbps Up. Which is very very sad. This looks like some kind of src-NAT-ing / connection tracking / packet queueing issue.
With 6.0rc5 I have 100/~30Mbps, but if I upgrade to 6.0rc6 it's back to old "good" 100/15. That's sucks. Web-Proxy is not a solution for me due to multiple reasons. Any creative advice are welcome. I'm considering to purchase CCR router, but if that one has same issue, I will laugh an go with a basic Cisco ASA for "slightly" more money... :(

This material is no proof of anything. Unless your ISP makes proper engineering measurements (they know and control their network) - you cannot yet prove the issue is in the router that you have.

can you make an drawing when you are satisfied and example drawing when you observe the "problem" ?

Can you remember if all conditions are the same when you compare? Including hour of the day ;)

Don't be sad, OK - you can figure it out I am sure.

What model router are you trying this with and with what amount of packets per second VS megabits ? :)

Above speed tests are not proving that MT is good or bad, they just proves there is a performance difference between two release candidates. ISP can't guarantee anything since they have dozens of peering partners use lot of IP transit providers and path to the destination is dynamic (lot of hops, all under different ownership) - So real Internet. There is two things we know. MT is attached to core switch which has several 10Gbps uplinks everywhere. Destination link is underutilized on first two hops (rest is unknown), but we know that it works as expected if server is attached directly to the network without MT router. It works with Cisco ASA as well, even more OpenWRT based SOHO toys like LinkSys, TP-Link, D-Link stuff works properly. So even I can't prove it, tests shows that something isn't as it should be in RouterOS.

can you make an drawing when you are satisfied and example drawing when you observe the "problem" ?
Well I have RB750G, RB750GL and RB2011UAS devices. All of them shows same issue. I'm testing with RB2011UAS right now. I couldn't make a any configuration which doesn't shows this behaviour. So problem exists even with factory default configuration. DHCP Client on WAN, masquerade, DHCP server on LAN; nothing else - so pure out of the box configuration. There are no packet drops on interfaces checked on both switches.


Can you remember if all conditions are the same when you compare? Including hour of the day ;)
Time and ROS version was different on above links. Time is an issue, but I did lot of tests and I can confirm that time of day is irrelevant in this case.

What model router are you trying this with and with what amount of packets per second VS megabits ? :)
I'm using RB2011UAS right now. SpeedTest use pure http file transfer like traffic, big packets on one way and small ack/syn packets in another way. Nothing special. Router is not overloaded; cpu peaks at <60%, but this is in case it can reach 80-90Mbps. During problematic uploads CPU runs on ~10-15%. (LCD is disabled since it consume 5-8% of CPU power).

Do you have any Queues in your config ?

can you test again and this time include traceroute with each speedtest.net test - you will have to traceroute to the actual IP that is the actual bandwidth test server (not speedtest.net)

P.S. check the source IP address (see a whats my IP site) is the same when you do comparison tests !!!

Hi NetworkPro,

There is no queues except of Interface Queues / only-hardware-queue on all interfaces.
Thankfully I'm happy man right now, since all destinations are running nicely using my RB2011 router. Even more I have nice results to Australia: http://www.speedtest.net/result/2418348959.png, If anyone can do this better from EU I'm looking for his/hers results. 8)

Thanks for your assistance.

I have identical problem on RB951 and RB2011 , 100 Mbit Download / 50 Mbit Upload and only half upload when using Mikrotik ( 21-22 Mbit ) , when connecting directly without router I have 50-52 Mbit.
I was trying everything , different versions of ROS , totally changing all network cables to cat6 shielded, changing of MTU / MRU / MSS / TTL,connecting using additional switch between pc and router also between router and internet, changing port speed in Mikrotik as well in PC , changing ports in Mikrotik to Master & Slave as well as just bridge them all, changing network cards in PC , trying different drivers ...
And nothing works :(

Same problem here. Upload speed to Internet is very low when directly connected to a MT Router (CCR,x86,RB750 all the same) but perfectly fine when connected by PPPoE.

I think MSS or MTU problem.

Anyone has a solution ?

In one of my tries , when I changed from 1 Gbit to 100 Mbit port LAN ( negotiation change ) in Mikrotik I had almost max upload but very low download ><

same problem here with RB1200.

on this thread "http://forum.mikrotik.com/viewtopic.php ... 63#p349563" i found a possible solution:
we spend all day debugging this issue, trying everything, upgrading routeros to newest version, playing with interfaces configuration etc.
and finally we found that interfaces from eher1 to ether5 are connected to gigabit switch, which is seen on this block diagram, so we thought that maybe it is a problem?

and BINGO!

we configured our LAN interface on eher8 and everything started working perfectly, max upload/download speeds are reachable without problems

then I add my interesting observation.
I also had earlier rb2011uas-2hnd-in , when I connected LAN PC to 100 Mbit switch , I had almost full download/upload , maybe was 2-5 Mbit less than max speed .
WAN was connected to GBIT switch.

Could you take a capture for a few seconds when you are doing your throughput testing? If you can put a link to an online download location where I can grab it I will take a look in at it and then see if there is anything appearing in there that would indicate a problem

Regards
Alexander

p.s. what ports are you connecting to your external connection and internal network and what devices are you using? also if you can provide an export compact of your config so I can take a look at this.

This post has 1 year and we have no response from Mikrotik. I didn't note this until now because i had an old SW Encore between my Cisco 757 LRS and my RB751U-2HnD and everything worked fine. Now that i have the Cisco 757 LRS connected to the RB751U-2HnD when i try to upload files through the Mikrotik speed is 15KB. I tried updating RouterOS but i still have the same issue.
Crossed cable didn't help.

Ethernet ports are likely to blame here as well:
http://forum.mikrotik.com/viewtopic.php ... 84#p394584

What is going on with the ROS ethernet stack and their HW? Why is it so hard to get it solid and bug free? Should we RMA all our devices and wait for the better patch to emerge?

Re: Slow Upload Speeds on Internet Port

Hi All,

I am experiencing the same problem but today ran into a very strange situation that may be useful to others.

Our environment is as follows:

RB450G(v6.7) --- Wireless Motorola P2P600 Link --- RB450G(v6.7)

This environment worked well until last week, then we began seeing 70Mbs / 2Mbs on the link. (The link is usually around 50Mbs symmetrical)

We test speeds between the two Mikrotiks using the tools > bandwidth test every time for consistancy.

Now... here is what we see currently...

If we test using TCP we see asymmetrical speeds of around 70up/2down *bad*

If we test using UDP we see the speeds eventually climb to reach 50/50 *good*

If we then test again immediately, using TCP, we also see 50/50 *good*

But, after a while the ratio returns to around 70/2 until we run the UDP test again and everything comes good again - for a while. Going in circles.

I have no solution yet, but this is just weird. Maybe it is the PTP600, maybe not. But the symptoms are the same as is being reported here.

Perhaps others could try the TCP and UDP tests to see if it makes a difference for you.

If I discover anything else I will report further.

Regards, Brian

Hi,

It's an old post but it seems that i had a similar issue...

in my case turned out to be a wrong use of the firewall - only had block rules inside and nothing for established related allow.

Thought they will get a allow at the end of the list anyway if i don't have a any-any block

I get 150/50 from my isp,

without est/related rules it's something bout 50/30 - wired!
with est/related 100/40
with est/related + est/related Fasttrack 150/50 :-)
