throughput of site2site-VPN

[Kleber_Nunes]

Hello friends!

I created a VPC connection with AWS to transfer some applications, but I noticed that transfer rate speed have been too slow, it's taking hours to transfer 1GB of data, hope you guys can help me. I have a Checkpoint 13500 running R80.40 take 119.

sk105119: Best Practices - VPN Performance

Thank you for answering!

While it is certainly possible that your firewall is the bottleneck and some tuning as described in sk105119 posted by Gunter will help, dramatically bad performance through a VPN is likely to be an IP MTU/Fragmentation issue, see here: sk98074: MTU and Fragmentation Issues in IPsec VPN.  Easy way to test if this is indeed the cause is to measure file transfer performance between the same two systems over the same network path, but NOT inside a IPSec tunnel (SCP/FTP/HTTPS/HTTP is fine for this test).  If performance is substantially better outside the tunnel it is definitely a MTU/frag issue.

Thank you for answering, i'll definitely put that to the test!
