is xfs good if I have millions of files and thousands of hardlinks?

[Tomasz Chmielewski <mangoo@wpkg.org>]

I have a ext3 filesystem with almost 200 million files (1.2 TB fs, ~65% 
full); most of the files are hardlinked multiple times, some of them are 
hardlinked thousands of times.

I described my problem yesterday on linux-fsdev list:

In general, because new files and hardlinks are being added all the time 
and the old ones are being removed, this leads to a very, very poor 
performance.

When I want to remove a lot of directories/files (which will be 
hardlinks, mostly), I see disk write speed is down to
50 kB/s - 200 kB/s (fifty - two hundred kilobytes/s) - this is the 
"bandwidth" used during the deletion.


Also, the filesystem is very fragmented ("dd if=/dev/zero of=some_file 
bs=64k" writes only about 1 MB/s).


Will xfs handle a large number of files, including lots of hardlinks, 
any better than ext3?
