1) I just made a "C# Aurora v0.x Questions" thread: http://aurora2.pentarch.org/index.php?topic=10097.0
Going forward, could everyone please put questions like this one in that thread? If we don't, then Steve's posts will age off the front page VERY quickly, which I don't think any of us want.
2) Several (maybe 5-7) years ago Steve made a major performance change so that the DB is only hit at the start and at the end of movement. IIRC that solved most of the disk I/O bandwidth problems and put the performance bottleneck back on the CPU. My recollection is that it was too hard to solve the N^2 complexity for sensor detection phase though, which is what's burning up the CPU. Happy to be correct by someone with experimental evidence that SSD is a lot faster, (or a better memory ) though.
Thanks,
John
