Another significant change in build times this week - not complaining, just my observations on build times; same server doing buildworld during the various phases of compiler changes over the last year or so FWIW: |--------------+--------------+---------------+----------+-----------| | Ver (svn-id) | World (mins) | Kernel (mins) | Relative | Comment | |--------------+--------------+---------------+----------+-----------| | 292733 | 90 | 16 | 0.5 | | | 299948 | 89 | 16 | 0.5 | | | 322724 | 174 | 21 | 1.0 | clang 4.x | | 323310 | 175 | 21 | 1.0 | clang 4.x | | 323984 | 175 | 21 | 1.0 | clang 4.x | | 324130 | 285 | 21 | 1.6 | clang 5.x | | 324204 | 280 | 21 | 1.6 | clang 5.x | |--------------+--------------+---------------+----------+-----------| Dan

On the other hand, I'm having tremendous increases in Unixbench scores comparing to 11-STABLE in the April (same machine, clang 4 then, clang 5 now) (about 40%). I have never seen something like that, and I'm running Unixbench on -STABLE since 2008. -- Sent from: http://freebsd.1045724.x6.nabble.com/freebsd-stable-f3932046.html
