It takes about one or two seconds (reasonable).
It takes about half a minute !! (too slow ;-)
I did simple performance measurement of SSL DeleGate to see roughly how the overhead is reduced with what device. Basically, DeleGate is executed as follows under the "time" command in csh.
delegated -P9999 -f SERVER=https STLS=fcland accessed with URL "https://localhost:9999/-/builtin/icons/" reloading five times, generating 300 HTTP requests. The result of the measurement is shown below and it can be summarized as follows:
