Slow write to flash in linux

If the speed starts to fall hard when uploading files to flash or movie is copied to an hour and even more, then the following will help.

The first thing you can do — put the

apt-get install gnome-commander

But in this version, if you have KDE, you will download and install automatic any libs. If you do not fit, move on to the next option.

Problem is in interrupt handling kernel. Do

grep usb /proc/interrupts

16:    5264887    5197915   IO-APIC-fasteoi   uhci_hcd:usb5, HDA Intel, nvidia
18:          0          0   IO-APIC-fasteoi   uhci_hcd:usb4
19:          0          0   IO-APIC-fasteoi   uhci_hcd:usb3
23:     508188     502178   IO-APIC-fasteoi   ehci_hcd:usb1, uhci_hcd:usb2

See 16, 18, 19, 23 interrupts.

Do
echo 1> / proc/irq/16/smp_affinity
echo 1> / proc/irq/18/smp_affinity
echo 1> / proc/irq/19/smp_affinity
echo 1> / proc/irq/23/smp_affinity

Copy to the stick.
