8NOTE TO PEOPLE WHO THINK THAT 5.0-CURRENT IS SLOW:
9 FreeBSD 5.0-CURRENT has many debugging features turned on, in
10 both the kernel and userland. These features attempt to detect
11 incorrect use of system primitives, and encourage loud failure
12 through extra sanity checking and fail stop semantics. They
13 also substantially impact system performance. If you want to
14 do performance measurement, benchmarking, and optimization,
15 you'll want to turn them off. This includes various WITNESS-
16 related kernel options, INVARIANTS, malloc debugging flags
17 in userland, and various verbose features in the kernel. Many
18 developers choose to disable these features on build machines
19 to maximize performance.
20
21 In addition, IDE write caching is currently disabled by default
22 due to on-going concerns about disk write order and file system
23 integrity. Re-enabling write caching can substantially improve
24 performance.

27 Warnings are now errors in the kernel. Unless you are a developer,
28 you should add -DNO_WERROR to your make line.

9 sendmail 8.12.2 has been imported. The sendmail binary is no
10 longer a set-user-ID root binary and the infrastructure to support
11 command line mail submission has changed. Be sure to run
12 mergemaster (especially for updating /etc/rc, /etc/defaults/rc.conf,
13 and /etc/mail) and read /etc/mail/README for more details.
