Hello all,
What parameters on a Cisco firewall FPR2140 connected in 10g (and I would say a firewall in general) could explain why a TCP flow is limited to between 370 and 430Mb/s while different test with iPerf showed the following :
- 1 TCP flow : max about 400Mb/s in average
- multiple TCP flows : multiple rates lower than 400Mb/s but sum about max 1Gb/s
- UDP : up to 4,2Gb/s
- TCP test without the FW in between : about 1,8Gb/s
thanks in advance
