Restarting computer speeds up render times?

I have this issue frequently, but last night was the biggest example of it.

I have a scene with 3 figures in it and last night it was rendering at about 1 iteration every 20 seconds. Very slow. Restart my computer and now its rendering an iteration every 2 seconds. TEN TIMES faster.

As I said, this is something that happens frequently. Last night was just the one that got me to post about it.

This happen to anyone else?

    It probably means that Iray had dropped to CPU, due to running out of memory. Often it's enough just to rstart DS to free it up but a full restart would probably free up some more memory from other processes too and allow a mrginal scene to render in the GPU.

    It happens to me quiet a bit.  I have been googling and reading a lot on the issue but I still have no clue how Iray manages VRAM in DAZ.  Some times I could do multiple renders all in GPU without exiting Daz and there were times Daz drops to CPU just after switching on and off a few Iray Preview.  In those caes sometimes restarting Daz program would refresh VRAM calculation and others times it won't and requires a computer restart, that is if I don't get a BSOD before that.

    Yep. I have restarted to improve render speeds also. This only started recently in the last year.
