I've got a problem with an Apache 1.3.33 installation on windows 2000 related to throughput, I can't understand what is happening. When I request a file from the local lan, the throughput is good and quite full, but when I fetch file from the internet ( we have a 180 KB/s link ) using clients with latency in average around 100ms, the total througput seems capped and limited to 40 KB/s . If I use the same client and I fetch the same file using the FTP protocol, I get full bandwidth usage ( 160-170 KB/s ). If I fetch the same file from an instance of IIS installed on the same server and same tcp port, the throughput is full, like FTP ( 160-170 KB/s ). If I fetch the same file from an instance of Apache version 2 installed on the same server and tcp port, the throughput seems again limited, but bigger than 1.3.33 ( 90 KB / s ). The file in question is 10 MB big. So according to this tests, to me it is not an ethernet interface problem, nor a wrong configured tcp ip settings, nor an in-path router/firewall that do bandwidth limiting. The only conclusion that I can make is that it seems that Apache sets or force the trasmit tcp window (not honoring client declared receive window, or host setting ) in some limiting way so that on high latency clients the problem shows up ( but not on local lan ethernet where latency is very low ). It is a known problem / how can I avoid the problem? Thanks you much all for your time .FT --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
