hi,

i heard they plan to move away from IAIK in direction of JSSE and/or open source
SSL toolkit but did not hear recently anything about it.

when we add HTTP keep-alive on client side then at least this cost will be only in
the first method call and next calls will be using already opened SSL channel ...

it *should* be faster!

SSL initial handshake is slow and using Java does not help. i do not think that
JSSE is much faster but do not have any hard data about it.

we did not do any real performance timings as we are more concerned with getting
authorization to work and we are still not there ...
