Binary and build lacks optimisations and RTCD resulting in slow operation #219
Description
I noticed that the operation of the VST plugin had slowed down considerably after the recent update, and while some slowdown is probably expected, I was able to build a binary with RTCD and MSVC /O2 enabled which brings the speed quite close to the old version.
This isn't a well working CI config, but the binary generated by that brought the time to process a 30 minute audio clip with Audacity from 2 min 20 sec to 50 seconds. The old version took around 40 seconds. Fixing this for the rest of the release binaries seems ideal
