How do I read this? The protocol and cipher are reasonable obvious.

This is the number of bytes that the client sends to the server, and then
the server sends back. Because this is all happening in one process,
the data is being encrypted, decrypted, encrypted and then decrypted again.

What does this all mean? Well for a server, with no session-id reuse, with
a transfer size of 10240 bytes, using RC4-MD5 and a 512bit server key,
a pentium pro 200 running linux can handle the SSLv3 protocol overheads of

Remember the first number is 1000 full ssl handshakes, the second is
1 full and 999 with session-id reuse. The RSA overheads for each exchange

cost would be quite similar in both the client and server.
