helo bashy..
like; some of us using eAcc or APC or Xcache for php accleration.
If u have Xcache installed on ur box for php cache/optimize u can install it for datastore cache.
atm we are on Xcache and it really works nice than eAcc.And it reduce more serverload than eAcc.
Xcache is perfectly working with php5.2.* series.
http://trac.lighttpd.net/xcache/
Xcache have option to cache php & variable.....to enable datastore cache for vb+xcache.
Gonna install this patch for data-store cache.
