Question Tuning XCache for VBOptimise

[fotografer]

Looking for some support to tune Xcache usage when combined with VBOptimise Pro 2.3.0 as we are getting quite a bit of OOM errors (on the assumption that less/no OOM errors is best).

Currently, XCache is set for 96MB PHP cache and 256MB VAR cache. The stats below show the usage and OOM errors.




From the var cache details, it seems that a lot of the cached data are not "hit" at all, which is weird.

Xcache var ttl and gc variables are :-

xcache.var_ttl = 900
xcache.var_maxttl = 1800
xcache.var_gc_interval = 300

I have also set the Global Cache TTL in VBOptimise settings to 900.

From the looks of the first graph you need to up your xcache.size and xcache.var_size.

I suggest you set them to 128 and 512 respectively.
