I've got an httpd stress tool that uses asyncore.  I can run up 1020 
independent simulated clients on my RH9 box(1x3Ghz cpu, 1GB ram), 
driving at over 600 requests per second against a modest (2x1Ghz) 
webserver, just pulling a static page.

Writing to files could slow you down a lot, depending on how much needs 
to be written, how fast your disks are,  how you go about getting the 
data from the async client to the file, etc..  Much of the same goes for 
sockets, too.

I should think all can do the job for you, depending on the details 
which you haven't told us.
