My website has reached the point where shared hosting is becoming a bit frustrating. Nothing dramatic, but the site gets noticeably slower whenever there are background tasks running.

I’m looking at VPS options in the $15–25/month range. I came across hostpro.com and their smaller VPS plans seem to be within my budget.

I’m not very interested in managed services because I’m comfortable with Linux. For a fairly small PHP/MySQL website, would you start with 2–4 cores and 4 GB RAM, or is that too optimistic?
