[TYPO3-performance] No results with eaccelerator

Hi Christian,

Same experience here: eAccelerator was faster than XCache in our 
benchmarks, though not by a huge amount.

We switched to XCache when Debian lenny was released as it was far more 
convenient than re-compiling eAccelerator from source every time the 
Debian team releases a new PHP security patch ;)

Best regards,
