class output cache: aren't there too many files in a single directory?

[quote author="atno" date="1306789707"]on unix systems with ext3 each directory can have up to 32k files/folders, yes you better split your cache files in multiple dirs within your cache folder[/quote]
Sub directories, yes, this due to the limit of links per inode. ext3 doesn't have a file limit.

I've had a directory with over a million files once, delay wasn't really noticable (with dir_index enabled). Most annoying was that most commandline tools stop working (forget doing an 'ls' in such a directory).
