If you are doing SSL termination without a hardware crypto accelerator then the cost of the public key operations for the SSL handshake will far outweigh the cost of TCP termination and the webserver. With a typical machine (say a 1 GHz P3) I would estimate you could do 200 SSL handshakes/sec with apache/modssl (with 95% of your CPU time spent in OpenSSL RSA code). With a hardware crypto accelerator you could get up to 600-1000 handshakes/sec but the crypto will still be the bottleneck.
