What's a reason of very slow writing to msdosfs (FAT32)? I get no more than 350Kb/s with recent 4.5-STABLE. Writing process spend much time in 'wdrain' state. 5.0-DP1 gives me 2Mb/s and more on the same machine. If I try to copy from one msdosfs to another msdosfs (both reside on the same drive) I get less than 160Kb/s.
