The following reply was made to PR misc/20555; it has been noted by GNATS.

How do you know top(1) doesn't measure CPU idle time on Linux differently than it does on FreeBSD? (I don't know whether they do or not, for the record, but I do know things like load averages are measured differently..) Plus, with no real way to "fix" this "problem", this PR is rather bogus. If it is determined that the 3c509 driver sucks in terms of performance, patches to increase its efficiency and such are quite acceptable. :) Besides, no one in their right mind that worries about performance is going to use a 3c509... -- Will Andrews <andrewsw@purdue.edu> <will@FreeBSD.org> GCS/E/S @d- s+:+ a--- C++ UB++++$ P+ L- E--- W+ N-- !o ?K w--- O- M+ V- PS+ PE++ Y+ PGP+>+++ t++ 5 X+ R+ tv+ b++ DI+++ D+ G++ e>++++ h! r- y?
