Hi All,

Following are the fireperf results I obtained:-

server: IPFire 2.25 - Core Update 153; Intel Celeron CPU J1900 @ 1.99GHz x4; I211 Gigabit Network Connection

client: Arch Linux; Intel Core i5-8400 CPU @ 2.80GHz 6 core; 1GBit nic

Server:
fireperf -s -P 10000 -p 63000:630010


Client:
fireperf -c <IP address> -P 1 -x -p 63000:63010 -> 100 - 3000 cps strongly fluctuating. After a couple of minutes the client cps went down to 0 and stayed there. I had to stop fireperf and restart the terminal to get it working again.

fireperf -c <IP address> -P 10 -x -p 63000:63010 ->250 - 500 cps fluctuating

fireperf -c <IP address> -P 100 -x -p 63000:63010 -> 220 - 1000 cps fluctuating

fireperf -c <IP address> -P 1000 -x -p 63000:63010 -> 1200 - 2500 cps fluctuating

fireperf -c <IP address> -P 10000 -x -p 63000:63010 -> 0 - 7000 cps hugely fluctuating


In all cases the cpu utilisation was quite low on both IPFire and the Arch Linux desktop.


I then repeated the above tests removing the -x option so I could see the data bandwidth.


fireperf -c <IP address> -P 1 -p 63000:63010 -> 225Mb/s - 1 core at 100%, rest around 30% to 40%

fireperf -c <IP address> -P 10 -p 63000:63010 -> 185Mb/s - similar as above

fireperf -c <IP address> -P 100 -p 63000:63010 -> 210Mb/s - similar to above

fireperf -c <IP address> -P 1000 -p 63000:63010 -> 370 - 450Mb/s - 2 cores at 100%, rest at 30% to 40%

fireperf -c <IP address> -P 10000 -p 63000:63010 -> 400Mb/s - 1Gb/s - 2 cores at 100%, rest at 40% to 50%


I recently got my Glass Fibre Gigabit connection connected. The supplier hooked his laptop directly to the media converter and got around 950Mb/s

Using the same speed test as he used but going through my IPFire hardware I get around 225Mb/s.

Although my hardware has four Intel I211 Gigabit NIC's, I have suspected that their performance is limited by the processor.
