Ok, was busy for the last few days optimizing for speed, hadn't done a tuneup in a while, managed to get some real improvements.

These quick tests were done to measure the "update load" -- the load caused by CSI just periodically updating the surfaces. There is no input (no button pushing etc.), this is to get a ballpark idea of just the refreshing that occurs all the time.

Happy to report update load down by up to 85% in some of the best cases.

The following tests were done on a late 2012 Mac Mini (2.3 GHz quad i7) running 10.14.6 and Reaper 6.0.

This is a 1420 Track torture test that won't actually run on this box, but you can bank the tracks while it is stopped, so it is valuable as a nice beefy test case.

The EuCon rig (2 Mixes and a Transport) is set up as a 512 Channel EuCon console -- took about 8 minutes for EuControl to concoct it, but it didn't fall over, and ran beautifully once it got online

Banking was almost as responsive as with the 16 Channel / 140 Track standard project used for everyday testing.

Here are the results of a few runs. These are for a single pass, usually the refresh rate for surfaces is set between 15 - 30 Hz so multiply these numbers by about 20 to get a feel for how much of a second CSI eats up -- hint - it's not much

A majority of tracks have an FX or 3 on them plus a few Sends.

Don't forget these are microseconds, divide by 1000 to get milliseconds.
