So say I need 10,000 tables, but I can create tablespaces.  Wouldn't that solve the performance problem caused by Linux's (or ext2/3's) problems with large directories?

For example, if each user creates (say) 10 tables, and I have 1000 users, I could create 100 tablespaces, and assign groups of 10 users to each tablespace.  This would limit each tablespace to 100 tables, and keep the ext2/3 file-system directories manageable.

Would this work?  Would there be other problems?

Thanks,
Craig
