This keeps the directory sizes down and allows for sound sets to be built up with all the words they use in them.
It also allows sounds to be added as needed rather than requiring all sounds to be part of a distribution.

Although the OS may cache that information, the userland process can take quite some time to process a very full directory. I've had this happen quite a few times with Linux ext2 filesystems, where the fileglob * exceeded bash's limit of 32,768 characters. /bin/ls on those directories took several minutes before the first results were given.
I'll additionally comment that the directories I was working with were not normally that full, but was a side effect of a process dumping lots of little files into a directory when something went wrong.
On a slight tangent, NT4 had a practical limit of about 300 directory entries before attempting to process the directory became unbearably slow.

A couple of things, searching a directory for a specific name tends to be a linear search through the directory (unless the filesystem uses binary trees, like ReiserFS...), "ls" is a bad example of a command, it is more of a worse case example.
ls will read the entire directory, sort it, then do a stat() on every file listed. All of this is done before it formats the output. So, you have to wait until it is all done, before you see the first character output.
