Hi everyone,

We just run performance tests on our new server that implemented using
WCF technology.
We see that performance over HTTPS much faster than over HTTP :-(
Both tests does exactly the same operation, same data, the difference
only in
configuration of SecurityMode that once is Transport (HTTPS) and once
is None (HTTP).
The test done on same couple of machines in both tests.
We have WCF client program that downloads 450 files (250MB) in
streamed mode
with encoding Text (we can't use MTOM because of reasons that I don't
want to explain here).

In case of HTTPS it takes ~50 sec and in case of HTTP it takes ~90
sec.
Is there any reasonable explanation for this strange behavior?

Thanks,
Maxim.

I tried Mtom but same result both works little (~10%) faster, but
still HTTPS is fatser than HTTP :-(

Just wanted to update everyone, that this magic problem resolved
by .NET 3.0 SP1 :-)
Thanks.
