Yes. The default is to create one inode for every 4k of disk space. So you'll
have about 11000 inodes for a 46MB partition (megabyte and not gigabyte right?).

If it's really 46MB you'll run out of disk space and inodes fairly quickly
You can do a 'df -i' command and find out exactly how many inodes are
allotted, allocated, and free.

ext2 does linear directory lookups. If possible I'd recommend subdividing
on something like the first letter of the account.
