In addition to other comments on this thread, please note that,
according to my _ballpark_ estimates, Squid "ssl_bump bump" performance
is about 10% of regular plain traffic forwarding performance and
"ssl_bump splice step2" performance is about 30%.
FWIW, we are working on significantly improving the latter:
