The PGO profile case runs the testsuite for php. This testsuite consists of over 16000 tests. See what we can do to reduce the number of tests ran during the profiling testsuite to reduce the buildtime whilst keeping the performance improvements.

Research direction
Start by locating the PGO profile case and the configuration that selects the PHP testsuite, then measure its current runtime and test count. Determine a smaller representative selection that preserves the stated performance improvements; done means the profiling run is shorter without a performance regression.
