This uses an SGThreadExclusive controlled by Emesary notifications that are received from the main loop. When active at the end of a frame the garbage collection thread will be released; if it is already running this will do nothing. Optionally at the start of the mainloop we can wait for the previous GC to finish. The actions of the background GC is controlled by notifications - again received from the main loop which in turn uses properties. I initially thought that the wait at the start of the frame would be necessary; however in 100 or so hours of flight without the await for completion at the start of frame no threading problems (or any other problems) were shown; so nasal-gc-threaded-wait is defaulted to false which gives a slight boost in performance. So what this does is to it removes the GC pause of 10-20ms every 4 seconds (test using the F-15). This change doesn't really give much extra performance per frame because normally GC is only performed when needed. |
