Hi guys,
first of all, this is the system iam using:
Ubuntu 14.04.3
Amd 15.12 Driver
AMD APP SDK 2.9.1
gpuPlotgenerator 4.0.3
Msi Gaming m3
Intel i5-6400
XFX r9 280x
32 GB DDR4
i have a problem with the direct plot mode of the gpuPlotGenerator. I only get about 2000nonces/minute in direct mode, plotting 3 files at the same time on differnet hdds. It took nearly 5h to print this files with only ca 170 GB ( each about 55GB).
I tried tweaking the device.txt and the staggersize, nothing worked. When i am plotting in buffer mode i get about 55000nonces/minute. (3TB in 3files took only 3h)
Now my question: Should the difference between buffer mode and direct mode be this big or am i doing something wrong?

Thanks for your help.
