What kind of system did you test this one? For example what does:
openssl speed rsa1024
give? I tried creating 1000 certificates on the fly and adding to the store.
The actual add took a couple of seconds. Having said that this is a fairly fast
system.
I've attached the program I used: let me know if that also takes a long time
to run.
