Of course there is a performance overhead. But for anyone that has problems with this a solution is pretty simple and requires few knowledge: remove these calls. Another solution would be to use one of the commercial or free script caches etc. I think the performance overhead is not so critical. But the ease of use advantage is considerable. Maybe someone with enough know how can look at the relevant code and see if there is anything in PHP that could be tweaked to make the performance overhead a little less, but even then it should be fairly minor. Then again I have not bothered to benchmark them. Regards, Lukas
