[TYPO3-UG Italy] 100%cpu

Mon Mar 10 14:50:30 CET 2014

Visto che la frequenza di svuotamento è frequente, mi sembrano tempi 
eccessivi per essere semplici svuotamenti di cache.
Oltretutto, sia su disco che su MySQL, dovresti avere tempi di attesa 
dell'IO, a meno che le operazioni non siano tutte in cache.

Usi OPEN_BASEDIR?
