Hello cpl,
Does anybody in here have experience with OPCache under windows?
http://nl3.php.net/opcache
It is bundled in PHP5.5 (and via PECL in earlier versions).
I installed PHP5.5.1 on a SBS2008 server under IIS7 (fast cgi).
After activating opcache, I used the suggested directives in php.ini, as
described here:
http://nl3.php.net/manual/en/opcache.configuration.php
It does show up now in phpinfo() as:
Opcode Caching Up and Running
Optimization Enabled
Startup OK
Shared memory model win32
Cache hits 12
Cache misses 15
Used memory 5752832
Free memory 61356032
Wasted memory 0
Cached scripts 15
Cached keys 21
Max keys 3907
OOM restarts 0
Hash keys restarts 0
Manual restarts 0
So far so good (I think).
Now I wonder: Is there any way to find out WHAT kind of performance gain
it gives?
I have a few ideas but I am not very enthusiastic about any of them:
1) Testing the time spend in the script: Not good, that is exclusive the
time needed to interpret the script (I expect, but I couldn't find a
decisive answer yet. If anybody knows, let me know please)
2) From end-user experience: Not good: If I time the responsetimes with
a clockwatch on my browser, I merely measure noise I expect: time spend
on the network, is the server busy doing other stuff, is the database
busy, etc.
3) Making a huge complicated script, and test it. Hoping the time needed
to interpret it is so long I can measure the difference as described in
2. (I haven't done this yet)
What would be a good way to test the speedgains by using OPCache?
Any ideas?
Thanks for your time.
Regards,
Erwin Moller
