--- Comment #11 from Vlad Movchan <vladislav.movchan at gmail.com> ---
Thanks for the feedback and attention to this bug.
I can't argue why using mutex-protected local cache of fpu_kern_ctx structures
was faster than allocating/deallocating this structures when necessary, but in
my tests mentioned in comment 2 it was so. Difference was clearly visible.
Unfortunately I can't re-run same tests as it seems I no longer own 1Gbps card
usable with NDIS - almost 7 years passed since.
