Hello folks,
i am pretty disappointed with the SSL VPN performance on TCP connections. When using TCP i only get ~16 Mbit/s when copying files over SMB. With UDP the performance is much better and i get the full 50 MBit/s. This is not acceptable at all, since i always got the full performance with UTM on even slower hardware and i need to use TCP on some sites. I've tested this on multiple appliances with our customers (XG210, XG125, XG115 etc.) and it's always the same: TCP performance on SSL VPN is plain bad and there is no heavy load on the CPUs involved.
Is this a bug, or is the TCP SSL VPN performance really that bad compared to UTM?
