Currently we started using HHVM in a production envirionment and so far almost all results are pretty inpressive. Our overall transaction rate is greatly improved compared to PHP-FPM with APC. Almost all requests are under 500ms however every couple of requests (5 to 10 or so) results in a request time of 2 to even 5 seconds.<\/p>\n
The page requested does not seem to make any difference and also requesting the same page over and over again will trigger this behavior within a couple of requests.<\/p>\n
We are running HHVM in server mode with the following command line options:<\/p>\n
\/usr\/bin\/hhvm --mode server -vServer.Type=fastcgi -vServer.FileSocket=\/usr\/local\/php55\/sockets\/admin.sock -vPidFile=\/var\/run\/hhvm\/admin.pid -vEval.Jit=true -vServer.ThreadCount=24 -vServer.APC.EnableApc=true\n<\/code><\/pre>\nWe are running nginx for the webserver with these relevant configurations (I am sorry if i forgot something importand here).<\/p>\n
fastcgi_buffer_size 128k;\nfastcgi_buffers 256 16k;\nfastcgi_busy_buffers_size 256k;\nfastcgi_temp_file_write_size 256k;\nfastcgi_read_timeout 240;\nfastcgi_intercept_errors on;\n<\/code><\/pre>\nThe server has 128GB of memory and 24 cores (hyperthreading so actually 12).<\/p>\n
We did a fair bit of searching on https:\/\/github.com\/facebook\/hhvm\/wiki\/Runtime-options however most options aren’t explained very well so I have no idea what they do and testing them in a production environment is a bit scary.<\/p>\n
Had anybody here had a similar problem or could maybe point me in a direction with some of the HHVM options I would be very grateful.<\/p>\n
The HHVM version used is from http:\/\/www.hop5.in\/yum\/el6\/<\/p>\n

Log {\n Level = Warning\n AlwaysLogUnhandledExceptions = true\n RuntimeErrorReportingLevel = 8191\n}\n\nMySQL {\n TypedResults = false\n}\n<\/code><\/pre>\nWe are using supervisord to start HHVM so here the supervisor config as wel:<\/p>\n
