Hmmm. It's quite possible, 3.x's getnewbuf() code is pretty nasty. I
have a solution under test for 4.x (current). There simply may not be
anything that can be done for 3.x short of porting current's getnewbuf()
code over, and doing so has been deemed too risky by DG due to all the
collateral porting that would also have to be done. I agree with that
assessment, plus it's a huge amount of work that I don't have time to do
at this late date.
Try using a smaller block size, like 16K. If that doesn't work then just
stick with 8K I guess. The kernel's clustering code should still make it
reasonably efficient.
