Plot time not as expected on the upgrade

[svennand]

Just got another plotter.
This is an HP Proliant G8,
It is set up with:
2x Xeon E5-2690 V2 10core 3.0Ghz
128GB DDR3 1333Mhz
4x Intel S3520 480GB SSD in software raid 0 (P420i set to HBA mode). NMON shows roughly 2000MB/s peak throughput
Using ramdisk 110GB, swap memory off, Ubuntu 20.4 from SD card.

With running -r 20 (or 40 doesnt matter), u 256
I get a plot time of 38min.

I was expecting alot better given that i earlier got 47min on my dual 2667 with 2x1TB samsung ssd, same memory 128GB 1333.

Anyone got any tips? When looking at nmon it seems the cpu isnt "hard pressed" running at around 65-85% on phase 1.

Down to 33 with setting the buckets to 512 :)
