Hi Derek,

>What is the realistic upper end of table file size before speed suffers? What about number of users accessing it?

That depends not only on the size of the table, it depends more on the network, the indexes, how many collisions might be there, the amount of RI-code in the database, whether you use Rushmore or not, how the database is structured, how much local memory you have. I think, it would be cheaper to upgrade all computers to 64 MB RAM and establish a 100MIPS network rather than trying to rewrite the application.
