mod_perl 2.0.2 + apache v2.2.3 from http://www.devside.net/server/webdeveloper
httpd.conf ThreadsPerChild 1920 ======================================================== I have a project must upload files to win2003 server. So i do the job by implement Protocol (Connection) Handlers in mod_perl. But the server will very busy when > 5 connections connect to apache at the same time. Maybe one connection upload big file (100M) . But in general the files is < 5M. The server have 4 cpu and Ram is 4G.But sometime the new connection will hang a little time (sometime can not accept new connections) .The cpu is not up to 100% and memory usage is still low.I have some problem want to know. 1. How the mpm_winnt work? It use one thread to keep the one request?Or it do many tasks by generate many thread on one connection? 2.Which one is more effective between Socket-based or Bucket Brigades-based Protocol? 3.The win32 task-manage show that the apache have 2 process.But sometime it have >2 process. Why? The apache use thread not process? 4.Have the Apache v2 mpm_prefork on win32? We testing the same code on linux.The performance is very very good than it on win2003 especially it have muti-connections on httpd. 5.Tuning the win2003 register will erase the upload file time. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\AFD\Parameters] "DefaultReceiveWindow"=dword:00019000 "DefaultSendWindow"=dword:00019000 Need i up the DefaultReceiveWindow value(>102400) to import the performance ?
