No, it cannot.

It depends what are you routing after. If you use ips it won't be a
problem. If you use regular expressions to match some parts of the
message then it's for sure more than 10, but I have no ideea if it would
be fast enough for 1000.
Just write a config with 1000 routes and give it a try :-)
