I'm one of guy who is not satisfied with composer speed. That's why I'm looking for a viable solution to speed up composer until I found HHVM made by Facebook. It is an open-source virtual machine designed for executing programs written in PHP. HHVM stands for HipHop Virtual Machine.
Install HHVM on OSX
HHVM can be installed using Homebrew. Please execute commands below in terminal
$ brew tap hhvm/hhvm
$ brew install hhvm
Grab a coffee, the build process really takes time :)
Install HHVM on Linux (Ubuntu 14.04)
It is great that Facebook provides prebuilt HHVM package.
$ sudo apt-get install software-properties-common
$ sudo apt-key adv --recv-keys --keyserver hkp://keyserver.ubuntu.com:80 0x5a16e7281be7a449
$ sudo add-apt-repository "deb http://dl.hhvm.com/ubuntu $(lsb\_release -sc) main"
$ sudo apt-get update
$ sudo apt-get install hhvm
Configure Composer with HHVM
You need to know the path of composer you installed by execute command below
$ which composer
Then we can add HHVM to composer command like below
$ hhvm your-composer-path
$ hhvm /usr/local/bin/composer
To make it simpler for future use, we can create an alias for it.
$ echo "alias composer='hhvm /usr/local/bin/composer'" >> ~/.bashrc
So your ordinary composer command is handled by HHVM.
To do the benchmark, I created a project with some packages defined. Then I measured the time between pure composer and hhvm+composer. I tested three times of composer install command.
Here is the command that I used for pure composer
$ time composer install
and for HHVM+composer
$ time hhvm /usr/local/bin/composer install
time is used to measure execution time. And here is the result
composer install 127.35s user 9.33s system 19% cpu 11:59.18 total hhvm /usr/local/bin/composer install 34.13s user 5.01s system 21% cpu 3:02.24 total
composer install 117.94s user 4.21s system 83% cpu 2:26.25 total hhvm /usr/local/bin/composer install 37.25s user 4.89s system 79% cpu 53.211 total
composer install 133.23s user 6.00s system 81% cpu 2:49.83 total hhvm /usr/local/bin/composer install 38.32s user 5.52s system 68% cpu 1:04.25 total
From the result above, we can see that the HHVM can really boost up the composer speed about 26 - 31%.
