Have you installed XCache as PHP extension? Would you please post your php.ini?

Amenadiel 03-02-2008 10:04 PM

Hi moo
such a nice work! my huge forum is on the fly with lighty n xcache

Opcode cache works like a charm, Variable cache is workin too but there is sth wrong with this class to me
it kills my forum when i swich datastore to this class! server load increases upto 12 then will changes frequency up and down
Im using XCache for Template Cache module without such problem! template vars are cached and they'r fetching as charm
but for datastore it s*x! sth wrong when cachin or probably fetchin

here is my xcache admin interface snaps which indicates what i wrote
Attachment 76647
and here is my xcache configuration using 8 splits due to SMP CPU ( Clovertown Quad Core )
Code:
[xcache]
xcache.shm_scheme =        "mmap"
xcache.size  =                32M
xcache.count =                8
xcache.slots =                16K
xcache.ttl  =                0
xcache.gc_interval =          0

xcache.var_size  =            32M
xcache.var_count =            8
xcache.var_slots =            16K
xcache.var_ttl  =            0
xcache.var_maxttl  =          0
xcache.var_gc_interval =    300

xcache.test =                Off
xcache.readonly_protection = Off
xcache.mmap_path =    "/dev/zero"

xcache.coredump_directory =  "/tmp/phpcore/"
xcache.cacher =              On
xcache.stat  =              On
xcache.optimizer =          Off

[xcache.coverager]
xcache.coverager =          Off
xcache.coveragedump_directory = ""
PS: i loaded xcache.so with zend extension, not default extensions directive

Please help me guys, any suggestion is welcome!

Regards

Seems config.php issue to me
make sure that ur config.php is clean by one $config['Datastore']['class'] assigned by 'vB_Datastore_XCache' and not commented out!

Thanks..
Ofcourse You can, theres no relationship between PHP Output handlers (GZIP or Deflate) and PHP Opcoder/Variable cachers ( XCache or APC or eAccelerator )

Amenadiel 03-03-2008 09:09 PM
Ok I solved the mistery. I spoke to the machine admin (I run the forum but I avoid messing with server configuration for I am no linux expert) and he told me that he compiled xcache without var cache support. He thought it wasn't necessary.

We will recompile in a few days. I'll update you guys then.

IrPr! You should increase the memory for op code cache. OOMs (out of memory) is no good. Try using 64 MB & see if there are any OOMs.
