Multiple Processors

[jOlsson]

I am running Retrospect 7.7 on a QuadCore Machine that has place for another CPU. Will I gain any performance in Retrospect by adding another CPU? Retrospect is the only (major) application running on this computer.

Unless you run software compression, the CPU is not the bottleneck. (i/o is the bottleneck)

Thanks Lennart,

so you mean it is better to add multiple NICs and RAM for better performance?

We also use software compression for backup to disk - do you think that Retrospect would use another CPU if I add one?

I don't know about 7.7, but 7.6 did not use multiple processors. You can add hardware cards for compression. There was a thread about that a while ago.

But since hard drives are so cheap nowadays, it's probably cheaper and faster to skip software compression.
