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. 25 2620020225: 27 Warnings are now errors in the kernel. Unless you are a developer, 28 you should add -DNO_WERROR to your make line. 29 |
