[Bug 492841] Re: open()ing files takes a long time with low throughput

[Phillip Susi]

I have been experimenting with patches to correct this problem.  I have
split the readahead into two passes where the first pass calls
readahead() to load directory blocks so that the open() calls do not
block waiting for them, then the second pass reads the normal files as
now.  I have also been resurrecting the old defrag package and using it
to pack the relevant files at the start of the disk with good results.
