Sorry for delay on this topic. I was awaiting new version of kernel. Anyway I have found the cause of it. It is hald with dbus which automounts the usb stick:
/dev/sdb1 on /media/usb0 type vfat (rw,noexec,nodev,sync,noatime,gid=46,dmask=0007,fmask=0117) this gives me 128KB/s. When I unmount it, mount it manualy (no sync), copy 15MB of data and issue time umount /mnt/ real 0m0.749s user 0m0.000s sys 0m0.015s Than it is very quickly. Probably the error is somewhere lower.
