In testing 3.0.0pre1 and now 3.0.0pre2 I have noticed that the rate
of data transfer is ~25% slower than 2.6.9. I am using rsync to
mirror 2 filesystems from a single host. On average for large files
(> 4gb) under 3.0.0pre2 the transfer of ~75MB/sec. WIth 2.6.9 the
average is ~105MB/sec.
I am compiling on a ia64 based system running SLES10 SP1 and see this
assembler warnings when compiling with gcc 4.1.2. Are these of any
concern?
