When downloading and transferring files when its downloading and allocating data read/wright my transfer rate is like 50KiB/s at most it will goto 200KiB/s
for drive sdb1 and sdb2
Yet when I download to my main drive that Mint 19 is on I get the full 300 to 500 MiB/s or more.
I did read up on https://stackoverflow.com/questions/305 ... r-than-8gb And I think this is some what related issue I have as I currently have 32GB Ram installed on my system
If you use a 32 bit kernel with more than 2G of RAM, you are running in a sub-optimal configuration where significant tradeoffs must be made. This is because in these configurations, the kernel can no longer map all of physical memory at once.
As the amount of physical memory increases beyond this point, the tradeoffs become worse and worse, because the struct page array that is used to manage all physical memory must be kept mapped at all times, and that array grows with physical memory.
The physical memory that isn't directly mapped by the kernel is called "highmem", and by default the writeback code treats highmem as undirtyable. This is what results in your zero values for the dirty thresholds.
You can change this by setting /proc/sys/vm/highmem_is_dirtyable to 1, but with that much memory you will be far better off if you install a 64-bit kernel instead.
nr_dirty 333
nr_writeback 0
nr_writeback_temp 0
nr_dirty_threshold 3840
nr_dirty_background_threshold 1920
How does one fix and resolve this issue on Linux Mint 19.1 Tessa. Thanks
