Hi,
while building our second server I noticed some differences of memory usage or let say RSS output from ps command.
Both servers are 8.2 amd64 and on both we installed the same jail. Output of syslogd and login process are roughly the same. The main difference is with php running in php-fpm sapi.
We build php from ports with the same params, so build should be more or less the same, right. But checking memory usage one one server php-fpm process uses 7200 RSS memory and on the other server it uses just 544 RSS memory. But funny thing is that not always
Sometimes RSS show 4376
Anyone know what could be the cause for such difference?
Results from
[CMD=""]procstat -v PID[/CMD]
1. 544 RSS
2. 4376 RSS
3. 7200 RSS
I removed the lines with zero RES
