The code itself looks good, I just need to double-check the
performance numbers.
I tested this patch on our VFS-specific version using five "prefetch
packs".
Before: 22.61 s (avg)
After: 22.18 s (avg)
Improvement: 2%
The error rate among the samples is very low (~.15 s) so this result is
significant.
Considering that we are writing 4.4 million commits -- many more than
the objects in the packs that we are reading -- this is an excellent
improvement!
Thanks!
