# Request for testers of and feedback on GCI-enabled OPcache - Thread: https://externals.io/message/67768 - Original archive: https://news-web.php.net/php.internals/67768 - Started by Terry Ellison on 2013-06-21T10:52:25+00:00 - Messages: 2 - Reply by email to internals@lists.php.net - More for agents: search with https://externals.io/search.md?q={query} · JSON API at https://externals.io/api · documentation at https://externals.io/llms.txt --- ## #67768 — Terry Ellison — 2013-06-21T10:52:25+00:00 URL: https://externals.io/message/67768#67768 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. --- ## #67772 — Martin Amps — 2013-06-21T23:01:22+00:00 URL: https://externals.io/message/67768#67772 · In reply to: #67768 When do you expect to have support for 5.5?
