Re: HYBRID VM

Hi, Recently, I committed HYBRID VM into master, but didn't enable it by default yet. It provides significant performance improvement on small benchmarks (1.5 times faster on bench.php) and slight improvement on real-life apps (1-2% on wordpress). Currently it improves PHP only on x86, x86_64 and PPC compiled with GCC. Anyone may regenerate and test it. php zend_vm_gen.php --with-vm-kind=HYBRID make

benchmarks for our inhouse CMS on my home-machine * Intel(R) Core(TM) i7-3770 CPU @ 3.40GHz * PGO-Build -mtune=sandybridge for our application there is real difference, just look at the two different runs with the hybrid-vm - which is at least not bad at the end "corecms" = a completly stripped own instance of our inhouse cms "contentlounge" = a expensive "generic formmailer" and other modules on the page the machine runs in a room with a high temperature and i faced larger differences even with the same build and nothing changed, maybe other applications will see more speed improvement, the codebase is highly optimized down to OPCODEs looking at xdebug-profiles and probably the most tiny codebase depending on the configured modules out there given a total LOC around 250000 lines in theory (but that includes also admin baclaneds for all sort of servers....) _______________________________________________________________ /usr/bin/php Zend/zend_vm_gen.php --with-vm-kind=CALL
