We tested the 3.7 package, from our point of view it is suitable to be released. But now it depends only on MT.

rastod

We do not have any problems with 3.7 build time Mar/27/2008.
We run it 4 days on 4 PPPoE server with 500-800 active connections each.
We have only little performance problems that are common for older versions 2.9.x

rastod

We use PPPoE servers for thousands of PPPoE clients and we never had such problem. Check your connectino timeout settigs may be. There were another problems on 2.9.5x.

rastod

Still the same, working fine..., no problems as before.

rastod

Don't wory, 3.7 seems to be really very good.
Running 24 hours, no problems yet.

rastod

Yes, I can confirm this problem too. I have ping to localhost over 100ms. After restart it is ok. I've already informed MT, they are working on it.

rastod

MT sent me to check corrections.

rastod

it seems they found. I am testing 3.7 and it works much more better...

rastod

I have reply from MT support, they confirmed problem and they are working on solution.

I use two radius servers too and it is normal that mikrotik do not go to the second radius when first one deny request.

rastod

It seems to be true - I watched log and ping and it seems that every time new PPPoE session is created or closed, packet lose occures. So, it seems there are two problems: - packet lose when creating/closing pppoe session - high ping response to locahost when higher utilization even CPU is about 50%...

rastod

I believe MT is working on this issue. But there is always workaround - use static queues or queue tree. There are also several benefits to use static queues: *) few queues, instead of hundreds for each user *) easy to manage *) reduced CPU and memory usage. Probably you can find more. We terminate...

rastod

Yes, I suppose that it can be problem. But in older versions it was correct. Maybe MT should consider this.
But not only packet lose, also high time response to locahost ping is problem. Maybe it is common problem.

rastod

I did, but still no answer. I wanted to check if there are others that meet the problem.

rastod

I have new observation.

When I switched off "Change TCP MSS" on all used profiles, so there were no dynamic iptable's Mangle rules, the problem diminish. It is still here, but not so huge.

rastod

At least, I am not alone.

And what are you doing now? Downgrade back to 2.9.xx?

rastod

Hi all, we have big problems with performance of PPPoE server running 3.x versions. Today we run 3.4 version and still having problem. The problem is that we have packetlose on localhost (127.0.0.1) and all interfaces. It seems like it is a performance problem or problem of interface queues. We run ...

Thank you, it works fine. The only problem is that the checkrad.pl script is very ineffective because it must read all interfaces from PPPoE server. Will MikrotIK update SNMP version to be able to find interface by its name?

and what HW do you use?

rastod

hi trtmrt
