wiggle Posted April 18, 2015 Report Share Posted April 18, 2015 I just upgraded to v12 for the speed improvements. I started a grooming (matching) and I see the process is at 100% (1 hardware thread), when I have 8 in my MBP and nothing else is running. This bottleneck has existed for as long as I can remember (I use Retrospect since the Cube). It is time to make such tasks multicore, at least 4 hardware threads for Desktop. BTW, I bought Desktop originally instead of Express because it supported tape, and I think it does not now (considering going back to LTO), and I only need to backup 1 or 2 computers.

Lennart_T Posted April 19, 2015 Report Share Posted April 19, 2015 The Desktop version supports a single tape drive. The Single-Server version support a tape library with a single tape drive. For most tasks, the bottleneck is i/o, not CPU. I think that Retrospect uses one CPU core per execution unit. Since Desktop is limited to one execution unit, it uses one core.

wiggle Posted April 19, 2015 Author Report Share Posted April 19, 2015 I can see for many years now in the system monitor that it is limited to 1 hardware thread per activity. I spend a lot of the time bottlenecked by this, so it is worth optimising (at least in matching, where I was seeing it now). I basically have no use for multiple concurrent activities.
