I should have mentioned in my last post that I’m using Secure Platform for the host OS.
I have double checked all interfaces and they are configured correctly. If you note from my last post the poor performance is with HTTP transfers. FTP transfers work as expected. Using FTP I have been able to push about 40Mb/sec to my FTP server in my DMZ on this firewall. I have also been able to download at about 15Mb/sec from external FTP sites such as Netscape. When you do the same transfer using HTTP I get 8-10x decrease in through put. I get the same results with IE and FireFox. If I use
www.microsoft.com/directx as an example, inside the firewall I average about 1.5Mb/sec, outside the firewall I average 10Mb/sec-15Mb/sec. I also see the same problem with our development firewall. I have tried disabling all SmartDefense checks on our dev environment to see if that was causing the issue but it had no effect on the throughput.
My CheckPoint partner has also witnessed this behavior with our system but has not received any explanations from Check Point on the mater. Is anyone else experiencing this behavior?
