I played a couple of small SnGs on pokerstars, finished up and took the cat for a walk. I left hand import running and the poker client sitting on the front lobby. I've had Task Manager running all morning to monitor CPU/Mem usage. The attached image refers.
I noticed that the CPU had pretty much topped out even though I was AFK for more than 20 minutes. Puter's hard drive access light was also working overtime. I put it down to PT4 doing some maintenance. I stopped hand import and CPU dropped down to squadoosh and stayed there... a little surprising as there hadn't been anything to import for a while.
I restarted hand import and CPU load went to back to approx 50% and stayed there. This is a lot of CPU load for something that is not doing anything.
Edit: HD access light still flashing like mad.
