Memory consumption problem, my blog suddenly uses 50 and then 200mb

Hi everyone,

I always have problems with my memory consumption, I don’t know if I have a lot of plugins or what… Here you are my list:

Do you know if any of it cause problems?

If I run the following command in the shell: [ps34739]$ for k in $(ps -u blah85 u | awk ‘NR != 1 {print $2, $6}’ | sort -k 2 -nr | awk ‘{print $1}’) ; do ps -p $k u | awk ‘NR != 1 {print $2, $6, $11}’ ; lsof -wp $k | grep home | awk ‘{print $9}’; done;

Appears me that… when I acceed into wp-admin panel…

(The first number is the proccess id, the second is the memory used)

22784 63532 php5.cgi
/home/blah85/cy/wp-admin
21616 51772 php5.cgi
/home/blah85/cy/wp-admin
20916 1800 -bash
/home/blah85
8930 1780 -bash
/home/blah85
18253 1772 proftpd:
20914 1744 sshd:
8844 1740 sshd:
[ps34739]$

Suddenly appears 65mb more… I really don’t know why… Is this normal? Sometimes the site tooks 200mb of memory with poor visits.

Do I need a Site Optimization?

Well… I hope your help.

Thanks,
Firk
