I have a wordpress blog, with complicated plugins and theme. I recently hit fatal error cannot allocate memory error on 256mb. 256 itself is allot, so I got rid of 1 plugin and it went back to 60MB, which still seems a bit high but ok.
My question is this,
How does php usage increase over number of users increased?
If I load wordpress dashboard and it takes 60mb of ram, will 2 users loading same page eat up more ram? (leaving aside all caching methods).
