I think you're being horribly optimistic if you actually want 10000
concurrent connections, with users all doing things. Even if you only
allow 1MB for each connection that's 10GB of RAM you'd want. Plus a big
chunk more to actually cache your database files and do work in. Then,
if you had 10,000 concurrent queries you'd probably want a mainframe to
handle all the concurrency, or perhaps a 64-CPU box would suffice...
You probably want to investigate connection pooling, but if you say what
you want to achieve then people will be able to suggest the best approach.
