Number of Files in PHP Library

[David T. Ashley]

Hi,

PHP allows the "library" which can contain an arbitrary number of include
files.

Can I put all the include files right in this directory, or should I create
subdirectories?

My question comes about because I understand that *nix systems begin to run
into performance difficulties at around 200 files in a directory (linear
search times for a directory).

Has anyone had experience with a large number of include files in a single
directory? How many? Did it seem to affect performance?

Thanks, Dave Ashley.

200 is way to small. More like in the thousands, at least on Solaris.
YMMV depending on the Unix variant. Besides, when you use readdir(),
you're scanning the directory linearly anyway, one line at a time.

This statement is both false as correct. There are *nix filesystems
which do re linear, there are also fs which use btrees: O(log n)
worstcase. So what system are you php running on?
