Subject: Request for testers of and feedback on GCI-enabled OPcache
From: ellison.terry@gmail.com (Terry Ellison)

The Multi-Level Cache (MLC) OPcache fork typically delivers 80% of the 
performance acceleration of standard OPcache for the CLI and GCI SAPI 
modes. (OPCache and other cache accelerators don't functionally support 
these modes). The last build is now pretty stable in that it runs runs 
the PHP test suite and MediaWiki under GCI happily. It also has greater 
savings for the I/O load associated with script compilation for these 
modes. (In other SAPI modes, it runs the standard OPcache functionality 
and therefore delivers 100% of the OPcache benefits).

However, I now need others actively to evaluate this alpha code and give 
feedback on its performance and its configuration interface if we are 
going to move towards promoting the introduction of this or some variant 
thereof into the PHP core. So my request here is to those CGI SAPI mode 
users on these lists to help support this work. Many of you have 
complained about the poor performance of PHP in CGI and now is your 
opportunity to help address this. You will find an overview of MLC 
OPcache at:

https://github.com/TerryE/opcache/wiki/MLC-OPcache-details

and can pull the latest code from:

https://github.com/TerryE/opcache/archive/dev-filecache.zip

If you would like to help then please download, build and try out this 
version, respond to https://github.com/TerryE/opcache/issues/3 and use 
the Github issues tracker for MLC-OPcache-specific discussion. Only use 
these mailing lists for comment that you feel has wider interest to the 
list subscribers.

Thank-you and regards
Terry Ellison

Caveat: I've only tested this Alpha version on 64bit Linux 
configurations for PHP 5.3 and 5.4, and would therefore like to limit 
initial testing to these configurations at this stage.
