Re: ST39103LC disk speed

Jim, for the lvm test, can you try the following :-

1. dd if=/dev/vgXX/rlvolYY (so raw lvol)
2. dd if=/dev/vgXX/lvolYY (block lvol)

Then put a large file on the lvol using prealloc and try dd'ing that file.

Using the file and block device will go through the buffer cache. The raw lvol and raw disk won't.
