IMO you should upgrade to VPS when you're site is getting errors all the time..
Daniel Reviewed by Daniel on . When should I upgrade shared to VPS? hello there Pro webmasters, newbie here. I need clarifications , when should I upgrade my currently shared hosting into a VPS (that's what I heard)?.. Does it count on the size of database and the traffic used?.. what is the advantage of VPS on shared hostings?.. Haven't tried that VPS thingy because I'm a first timer webmaster . How much size is your database as of now?.. mine, is only 15MB for 6months old site. Rating: 5
