A good friend of mine, Nicole, runs a travel blog called Bitten By the Travel Bug recently came to me with some WordPress troubles. Her WordPress install that deals with just under half a million hits per month is having a bit of trouble keeping up with the demand.

In this series I'll be investigating and documenting my findings, mistakes and fixes in the hopes that future developers - and maybe even future me - will find the information useful even if it only points them in the right direction.
