Back-tests are suddenly taking 3 times longer for me - I noticed CPU usage is maxing out at 35% when running BT's. This hasn't happened before, so I can't work it out? Does anyone know of any tools I could use to investigate the problem?
NOTE: A friend has exactly the same machine and performs exactly the same BT's at 100% CPU usage and completes the BT 3 to 4 times faster than me. Therefore clearly there is something wrong with my configuration specifically. Note also we are running exactly the same AB settings.
I checked the BIOS (and updated it) and all Hyper Threading / Turbo Boost / etc. was on.
I did make some progress: I updated to AB v 6.3 to test it and didn't realise that, as a trial, I don't think it was utilising the Norgate Local DB. When I rolled back to 6.2 I got a massive speed improvement.
However, it is still taking me 50% more time to run a BT than my friend with the same machine.
I've also ruled out Bitdefender. I am getting much closer to 100% cpu usage now, but it is not consistent. Also, if I run the AB Performance Monitor, cpu usage maxes out at about 60% (even when task manager says 100%), so I still don't think my cpu is being used fully. Perhaps it is a machine fault?
At this stage, I've tried everything I can think of : )
