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

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.
When do you expect to have support for 5.5? I’d be happy to test it on a few of our servers as soon as you are
