Seriously, 3123 files in a single directory is not an issue for any of
the extX filesystems. Though ext2 probably performs the worst, ext3 and
particular ext4 should not have any problem with that small amount of
file objects. Given that the filesystem is not already filled nearby 100%.

An issue may be, how the code deals with the directory content. Horrible
code for sure can impact the speed of the website, but should not affect
the system globally.

Yonatan, if you really are concerned about the uploads directory, then
use vmstat, iostat or sar to check system parameters while the directory
is accessed.

Your problem is something else, I am pretty sure.
