    CPU instruction cache misses are a limiting factor for the large PHP applications that Facebook runs, so a hybrid between interpretation and translation may outperform pure translation. One might assume these checks would be sufficient for the lifetime of the tracelet, but many simple operations in PHP are capable of having side effects that can affect correctness and safety.

    The tracelet generated by the first invocation A and the tracelet generated for the second invocation B would be linked together in a chain like so:. Consider the following example:. Most-liked Facebook pages Most-viewed videos in the first 24 hours.

      The difference between 8-second and 5-second reloads due to switching from HPHPi to the HHVM interpreter makes a big difference to productivity, and this improvement will be even more dramatic once we enable the translator. How well does HHVM work?
