When we build PHP and XHProf without optimisations but with debug (--enable-debug), everything becomes much slower than usual, for example, this timing is typically 12512-12600 on my laptop and our build server in such configuration.
It doesn't look like a problem for higher timings (e.g. the following test usleep(50000) works fine as it has larger tolerance). I thought that we can allow a bit of extra time to consider the latencies of such builds.
