Copy particles to ssd become slower than before

Hi all,

I have met a prolem that I cache the particles to ssd become slower than others on a cluster.My speed always <100M/s and others always 300M/s.I don’t know how come to this problem.Because maybe we use the same ssd at different time,but we didn’t have the similar cache speed.I think it’s very weird.Looking forward your advice.Thanks very much.

And I also have 300M/s before my cryosparc stop accidently when I memory is full.Now I have restart the cryosparc and the memory isn’t full,but the speed didn’t recover.
