Keep in mind these results are with a slow external drive, but yah fat32 sync performance is still really bad. This patch is just meant to make fat32 sync performance better, not necessarily make it usable for everyone [one step at a time and all that]. FAT32 sync is quite slow (see http://readlist.com/lists/vger.kernel.org/linux-kernel/22/111761.html ), so if you want fast performance [or have drives with limited write cycles] async is almost definitely the way to go. I have a patch [not this one] which adds a module param ("fast") which syncs the FAT tables after 30 seconds of no write activity, but I don't think the majority of people are interested in it.

Is there decrease case? I assume the result is same. So, we would need different approach. > diff -y stock/1k modified/1k > 1024+0 records in 1024+0 > records in > 1024+0 records out 1024+0 > records out > 524288 bytes transferred in 1.777250 seconds (295000 bytes/se | 524288 > bytes transferred in 1.764748 seconds (297089 bytes/se -- OGAWA Hirofumi <hirofumi@xxxxxxxxxxxxxxxxxx>
