25. TYPO3:
Flow:
core:
phpBinaryPathAndFilename: /usr/bin/hhvm
subRequestPhpIniPathAndFilename: false
Configuration/Settings.yaml
(configured for speed)
Use HHVM on sub-requests, too
for even more performance.

26. TYPO3:
Flow:
core:
phpBinaryPathAndFilename: /usr/bin/php
subRequestPhpIniPathAndFilename: /etc/php5/cli/php.ini
Always specify a php.ini or “false”.
Automatic detection will fail.
Configuration/Settings.yaml

36. Use HHVM as FastCGI backend
Server {
Type = fastcgi
FileSocket = /var/run/hhvm.sock
SourceRoot = /var/www/my-flow-site/Web
DefaultDocument = index.php
ThreadCount = 100
}

ProxyPass / fcgi://127.0.0.1:9000/var/www/flow/Web/
Apache configuration
location /_Resources {
try_files $uri;
}
!
