Description Lucky Green 2003-10-12 11:17:49 UTC 
Description of problem:

"openssl speed" on an Athlon64 test server using the RH beta for AMD64 reports 
922 1024-bit RSA signings per second. This is a tad less than optimized code 
on an 800MHz Itanium will produce on a CPU running at less than 1/3 the speed 
of the Athlon64.

How reproducible:

Fully reproducible.
 
Actual results:

922 1014-bit RSA signatures per second.

Expected results:

At least 3000 1024-bit RSA signatures per second.
Comment 1 Tomas Mraz 2005-02-04 15:56:11 UTC 
How does it look with the latest upstream openssl?
Comment 2 Tomas Mraz 2005-04-22 12:01:46 UTC 
Current Fedora Core devel package uses the optimized assembly code for BN
operations.
