| NOTE: This is an ADVANCED feature that improves performance but adds a lot of complexity! This is only suitable for production servers because workers won't pick up changes between when they spawn and when they handle a request. Phabricator spends a significant portion of its runtime loading classes and functions, even with APC enabled. Since we have very rigidly-defined rules about what can go in a module (specifically: no side effects), it is safe to load all the libraries *before* we receive a request. Normally, SAPIs don't provide a way to do this, but with a patched PHP-FPM SAPI you can provide a warmup file that it will execute before a request is received. We're limited in what we can do here, since request information won't exist yet, but we can load class and function definitions, which is what we're really interested in. Once this file exists, the FCGI process will drop into its normal accept loop and eventually process a request. |
