Hi php-general,
sorry if it is a wrong lists for this question.

I have read many articles/messages about using tmpfs store temp files,

for example, php session data, smarty compied templates and so on.

An obvious reason for that is: it doesn't matter about data loss caused by
machine restart/poweroff.

since it is not that difficult to restore files on a tmpfs from a disk-based
dir when machine boot up.

so may i put all my php scripts on a tmpfs to speed it up? would that cause
other issues?

thanks for your advices.

Considering that in the main PHP scripts are readonly, I would have
thought the normal file and disk caching of the OS would suffice.

normal file/disk caching of the OS works for small amount of files,
but when your apps has huge amounts of files, that doesn't work any more.
even with APC, it still cause many stat() system calls.
