Eh? My var size is 0. You saying I have to set this to the same as what the xcache.size is? (100mb). Really? That much?

More info on this woul be good. I just tried to install this and got errors. I didn;t change the var size from 0, plus I assumed the location of the attached php file.

Please can more details be added to this hack as I would like to use it.

Thanks.

i have updated the topic again.
setting "xcache.var_size not 0" is same as "xcache.size"
xcache.var_size = 10M or so is fine, just resize it for to fit your needs.

you gotta copy the content of the whole php file i attached into class_datastore.php, there's no new file is created or added

I gez u can ..i gez
to use this(this thread) mods..u must have Xcache install in ur box
Quote:
Download Win32AutoBuilds at here/XCache-VERSION-php-x.y.x-Win32-rREV.zip. This is an official SvnSnapShots autobuild, but NOT release version.
Check InstallingAsPhpExtension for instructions. (the doc is not updated for win32 yet)
It can be very hard to compile for Win32. If you're gonna do it yourself, Cygwin is required, and check the simple README to accomplish the complex job.

Disassembler is avaiable in source but missing one file due to license problem, so not built into win32 binary package. btw, disassembler isn't designed to work with commercal encoders/encrypters.
http://trac.lighttpd.net/xcache/wiki/Win32AutoBuilds

(The Author phpxcache can explain u better)
After u got xcache installed on ur Box..U can use this mods for datastore cache.

Thanks for ur interest. I will try to provide u some info..see it it helps u a bit..

See bellow xcache.ini of our box

Quote:
; select low level shm/allocator scheme implemenation
xcache.shm_scheme = "mmap"
xcache.size = 64M
xcache.count = 4
xcache.slots = 8K
xcache.ttl = 0
xcache.gc_interval = 0

; same as aboves but for variable cache
xcache.var_size = 64M
xcache.var_count = 4
xcache.var_slots = 8K
; default ttl
xcache.var_ttl = 0
xcache.var_maxttl = 0
;xcache.var garbage collect interval set to 6 hour.
xcache.var_gc_interval = 21600
Pls follow the red color text
xcache.size & xcache.var_size both set to 64Mb .
And ur using 100 Mb for xcache.size . :confused: did u really need that much memory ?:eek: we set 64MB.33Mb used and still 31MB is free out of 64Mb. when vbplaza on it just consume 3~4Mb more + few more php cached.

check ur xcache admin cp & if needed reduce allocated memory OR if u got enugh memory at ur box/server ..then u can use 100MB+100 Mb.

Point is that u have to put same MB of memory at xcache.size & xcache.var_size

php file in the attachmnet

So I need to replace the class_datastore.php file with the included file (renamed)?
