Plot time increases after 1st plot.

[ablocks]

Anybody facing similar issue? I'm scratching my head over this..
I'm using bladebit 3.1 to create C7 plots on Ubuntu 22.04, Nvidia 4070., 128GB RAM and two 2TB NVMEs (one for temp and one for final plots). Computer is not performing other task at all (not even moving plots to my final location). First plot creation is around 4 minutes then other plots, plotting time increases to about 10 minutes. I tried to create only 1 plot then start over the process but result is the same. Restarting is the only solution to make plot time go back to 4 minutes. Any idea what might be happening?

Thank you!

Total plot time for the 1st plot: A bit over 4 minutes
Total plot time for other plots: about 10 minutes.

Non enterprise ssds tend to greatly reduce the write/read speed as the filled space increases.
Try to benchmark your ssd while it is empty and full and see the difference.

Hello. That is not the case as it doesn't matter if ssd is empty of full, plot speed increase a lot after the first plot.

I may have a similar problem...
I can have dozens of 10 minutes plots on 2 brand new nvmes alternating t1/t2/output but sometimes the plot time increases to 30 min until i restart the PC...
Plotting on Windows with 128gb ram and r7 7800x3d
I cant find the reason....
NVMe has its own 120mm fan so temps are quite whithin specs mostly of the time.
