Painful Speed for USB Transfers? Dirty Bytes!

Since my upgrade to newer distros, I was suffering from really slow USB transfer speeds.  Copying a large file to a USB stick would take long minutes and, although the process was eventually completed, I needed a lot of patience.

Then, I started trying different solutions but none seemed to work until I found this one.  It was about a problem that was exactly like mine.

It is very simple.  You just need to find the etc/sysctl.conf file and add the following line:

vm.dirty_bytes = 15000000

That's it.  With that, copying a 1.2 Gb file took me about 4 minutes and the progress bar was showing the information fine.

Right, it's not the fastest speed, but at least it is way better than before.
