I remember I started off with shared hosting. And i had to upgrade to VPS because my forum was becoming really slow and always getting "max user connections" My forum currently runs fine on VPS. Althought it got my wondering. How many users can a VPS handle? And what would be the next step. Dedicated Servers? How many users can a dedicated server handle? And is there anything past the dedicated server? How do those forums who have over 10,000 users online at the same time work? Anyone want to give us a brief outline? I can't find anything on google to read.
