I updated my computer recently to make this process faster, quad core cpu, 4GB ram and 2x seagate 7200rpm 500GB drives in RAID-0. I know SSD would of been better but I had to save that for the next upgrade.
Anyway I started importing a 1 million hand batch and was getting 80+ h/s, which I knew was too good to be true as I've read around 30h/s is a good figure. By the 100k mark it was still doing 50+ h/s. I went to bed and when I woke up it was only doing 6h/s. I vacuum analized, reindexed, and got it back to 35 - 36h/s, which I am happy with. My question is: When importing such large amounts of hands is it better to break them down into smaller batches 50k - 100k and then import?
My second question is about the defrag. Can I defrag my disks even though they are running in RAID-0?
