I tend to agree. What kind of disk setup is under your data store?
If it's RAID-5 or RAID-6 is it possibly degraded?
I'd run iostat -xd 10 while the write load it high to see how your
xlog partition %util compares to the main data store partition.
Do you have your main data store partition under a battery backed
caching RAID controller? Tell us what you can about your hardware
setup.
