Hi, I have been trying to profile apache 2.0.55 using Gprof by compiling it with "-g -pg" option.The mpm used is worker. MaxRequestsPerChild is changed to 1 in httpd.conf and I Start apache with "httpd -X" option and make a single and then stop it.The gmon.out file produced does show some details but when I make multiple requests say , 10 thousand requests , although the number of calls are recorded it doesn't show up time used by those function calls. It shows up as 0.00 . If the server takes lets say , 10 minutes to serve/process the ten thousand requests , shouldn't it be reflected in the gprof output also ? could it be multithreading issue because of worker mpm? or does gprof only shows time for a single function call rather than a cumulative amount of time used by all the calls made to a function ? Any help will be appreciated and thanks in advance. -Paras --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
