There is no particular threshold. The more files you have in a directory,
the longer it will take to list everything. You must simply experiment
until you find an acceptable balance.
I would be inclined to start from the other end. Figure out what files you
don't need and archive/delete them every day. If that doesn't help, be more
Separating the various types of files into different directories would help.
