For my forum (3000 users, 700000 posts, usually about 150-200 users online) I have a VPS with:
RAM 3072 MB
Discspace 30 GB
CPU-cores 2 × 2.4 Ghz @ 80%
my database filesize is 1GB
Will it improve the page load time of my website if i get better cpu, more ram or more discspace? I am using the latest ipboard with wordpress via ipsconnect.
Also, I couldn't find much about mod_pagespeed here. Is anyone here who is using it and is seeing improvements in their page speeds?
