Guys,
as you know I am performing a set of volume tests on OpenCA 0.9.2 RC6 (recent CVS). My first set of tests are volume testing the batch processor (i.e. seeing how the performance varies with batch size). I have noticed this:
As the batch size gets bigger, the time to complete the batch increases in a non linear mannor. some examples are:
100 batch 2 minutes 11 seconds 1000 batch 33 minutes 22 seconds 3000 batch 3 hours 30 minutes 43 seconds
I suspected that this was a memory issue, i.e. the server process not giving up it's memory, this was confirmend when I tried a batch of 10,000 and got the following error after 8085 items in the create_cert function:
New statemachine cycle at Tue Aug 31 13:11:46 2004 UTC ... The function create_cert
There is a problem with function create_cert for process keys of user p98KfYKP_8085.
Cannot issue the certificate (6761). Error while issuing Certificate to p98KfYKP_8085 (filename: /usr/local/volume_ca/openca/var/tmp/1FA4.req).
OpenCA::OpenSSL returns errocode 7731075 (OpenCA::OpenSSL->issueCert: OpenSSL fails (7777030). Cannot start OpenSSL shell. (Cannot allocate memory)).
Looking at the SAR output the machine is running at 99% memory usage during these tests.
I would be very interested in your comments on this.
Chris...
