Quoting Will Ashford (washford at cs.stanford.edu):

That makes sense -- and asymmetric ciphers are well known for being much
more computationally intensive.  And yes, the session ciphers are
invariably symmetric ones.

That leaves hash algorithms, of course, but I guesstimate that they're 
relied on much less often.
