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....)
