Re: [Bacula-users] Performance problem with baculas encryption system

Any chance you can run this under a profiler? I haven't had time to look at it since I wrote it, but my last tests demonstrated that RSA signing took up the vast majority of the runtime.
I hope this is what you wanted :)
Since there seems no difference in the profile, how could I check if signing is really deactivated (or activated) ?
