--- Comment #25 from Tavis Paquette <tavis at eventbase.com> ---
write-behind was enabled in the scenario where i was experiencing low write
performance

turning write-behind off seemed to bring my write throughput back to 3.7.6
levels
the profile was generated on a cluster that had write-behind disabled

i'll try to find time to generate a profile with 3.7.6 in the same
configuration, as well as 3.7.8 with write-behind enabled and then 3.7.8 with
write-behind disabled

it may take me a few days though, i'll follow up as soon as i can
