Performance difference SOAP with and w/o SSL

Vlado

Has anyone compared the same archive job with and w/o SOAP over SSL? What is your experience?


I realized a big slowness archiving with SSL in two environments. 20 to 50 times slower. In my opinion, 50-100% slower can be acceptable.

Support  confirmed it in their lab.

Here are couple of examples. Just using the same Profile (All Items in Mailbox) and switch SSL on or off.

    given that encryption is a CPU intensive operation, how busy are servers on either end?  perhaps one or both is CPU constrained with SSL turned on, and just adding cores speeds things up.   check RAM as well, though not as critical as CPU for this.

    The speed degradation is certainly not reasonable or a match to any other SSLized operations I've seen before, hence I suspect a resource constraint.

    Exactly this is a reason why I asked community for experience in comparison of performance.  Of course SSL need more resources, but 40-50 times slower is too much.

    I think I have more then enough resources. Both server are less then 10-20% on CPU and have enough free memory.

    I have same speed as you, between 1 - 2 m/s, I had here thread about speed and I was the slowest one. Plenty RAM, unlimited CPU, very quick SAN and this kind of performance.
