I've recently have this issue that moving files takes a lots of time, at

100/200KB/S. My usb flashdisk is 4gb formatted in fat32.
It seems to me it is related to kernel.Anyway here is my info :
Do you have the "sync" option for fat32 enabled? If so, that will cause
this to happen. Several distros enabled this a while ago to ensure you
would get the data written out quicker.
I guess it is turned off.At least i turned it off with every solution
posted in internet, such as creating mount policy, unmounting and
remounting with mount async option, also used 3 different versions of
kernel and all seems to suffer from this.
Besides, enabling sync option and having slow performance, couldnt this
also considered as a bug?
Thanks
