Hi @nfrasser.
The performance improved, but it is quite obvious that when two processes try to access the same resources, it slows to a halt. Since you referenced the SSD caching, I have been paying closer attention to this, and it does seem that the reading in of images is slow as heck if two processes are trying to read the cache in.
Is there anything that could be done about it? In 2.15, this was never an issue.
Best,
