hEX performance numbers? Some clarification for a newbie...

RouterOS General

Hi,

So I see the performance numbers have been put out on routerboard.com for the hEX RB750Gr2.

Based on 25 IP filter rules it looks the throughput for 1518 bytes is 986.1 Mbps. Does 1518 relate to the MTU size, or what number is the most realistic to use for determining WAN to LAN performance? Sorry if this is a newbie question.

Further - it also appears that this has better performance than the RB2011 - which is surprising… or am I missing something?

Thanks

RB2011 is much older, so possible that hEX is faster, yes.

Byte size depends on traffic, usually people have many kinds of traffic, downloads, Skype calls, torrents, web browsing, FTP.

Thank you so much for the reply - but in general terms what size should I use to estimate WAN to LAN performance from the data?

You can’ estimate.
Think how many times some “people” estimated the end of the world…

I am just trying to understand what byte packet size is best used or most representative…

IMIX is an attempt at answering your question:

https://en.wikipedia.org/wiki/Internet_Mix

From that, we can assume that 58% of your traffic will be <58Mbps , 33% will be <~480Mbps and 8% will be 986Mbps.

With any luck your existing equipment might let you work out the distribution of packet sizes across it? You will probably find it approximates the IMIX figures.

I am estimating according the last row from the performance table (routing with 25 filter rules) 512B column. This is the most representative value that roughly corresponds to my cases when a device should do the nat. And the values are quite similar in real.

Thank you - this is exactly the information I was looking for.
