It is a fact that the access from internal flash is slower then internal RAM, that is the reasn they have MAM setting.... it actually caches the instructions and execute from the cache, which results in faster execution. there are three different settings .. 
MAM -- off  --- slowest 
MAM  -- partially on -- Execution time more predictable 
MAM -- full on... best executin time.

  Runing from RAM runs at Cclk. Flash has 60ns access time, which is 3x 
  slower at 60MHz. Are you using MAM?
