svnadmin load using fsfs is agonizingly slow

We have several repositories and our largest repository when svnadmin dump'd
is approximately 71gigs in size (Takes a very long time to dump even though
all users are kicked out of the repository so no changes will take place.)
Restoration of this repository using svnadmin load has currently taken over
48 hours and is still NOT complete. I have read some threads that specify
that fsync is the problem when using BDB but I have not seen any threads
with a recognized issue regarding FSFS. In addition are there any settings
that I can use to disable fsync during a load? Or any other optimization
techniques that I can use for svnadmin load with an FSFS type repository?
And just to head things off at the pass, I dumped my repositories because I
am upgrading from 1.3.2 to 1.4.0 and wanted to make sure the repositories
were using the new 1.4 format.
In addition this is a dual processor, 2G RAM, 1.5 TB RAID 5 system that is
showing less that 2% CPU utilization and is only using 108M of RAM so it is
definitely NOT the hardware.
Any advice or guidance would be greatly appreciated as I have engineers who
are looking to lynch me and I would like to avoid a fiery death.
Thanks in advance,
