Neo-match
I still remember that the last time I saw the article optimized about FreeBSD 5 was 1 year ago, it was also when I just started UNIX. Time flies, I learned a lot of FreeBSD and UNIX knowledge in this year, and I am interested in how FreeBSD is more interested. Now, FreeBSD has replaced my Windows2000 and becomes the only OS in my computer. Experience is not exclusive. Here, I would like to have all FreeBSD enthusiasts, if there is an improper, welcome to criticize criticism.
· This article assumes that the reader has read the FreeBSD installation manual. · When reading this article, be sure to refer to the installation optimization article. · This article follows the GPL protocol. · This article follows the BSDL protocol. · Welcome other authors to write a variety of FreeBSD optimization articles in conjunction with this article.
First, installation (sysinstall)
1. In Distribution, only MINIMAL is selected, select Customization. Adding a man, you can view the command parameters when you have a problem; add the SRC, then CVSUP can speed up the speed and do not read the repeated file.
2, in User, after adding the user, change the / home / abc in the user path to / usr / abc. Because / usr has large capacity. Or can also increase the capacity of / home, but it is more troublesome. Then, to change the shell to CSH, in order to use convenience (also for the setting of the seventh part of this article).
Second, compilation optimization (make.conf)
Note: To block a Boolean option, not tagning NO or FALSE! But delete!
1, compiler option
CPUTYPE = Athlon-xp ## I use Athlonxp 2500 , different CPUs, please refer to Man make.conf
Cflags = -mfpmath = sse -mmmx -msse -m3dnow -maccumulate-outgoing-args -minline-all-stringOps ## is not recommended to use O2, O3, OS optimization, because all applications can be stably operated in O2, O3, OS. Moreover only 7% of additional performance. ## cflags default is "-o1 -pipe", no need to overwrite, so use =. ## Not recommended to use -f ... series optimization because it is not all applications to stabilize this.
## -mfpmath = SSE: Pentiumiii-compatible CPU can open -mfpmath = SSE to replace the floating point operation of traditional i387, speed up the speed. See the CPU product manual to determine if the CPU contains the SSE function. ## -mfpmath = PNI: Pentium4 Prescott Compatible CPU can open -Mfpmath = PNI to replace the floating point operation of traditional i387, speed up. See the CPU product manual to determine if the CPU contains a PNI function. ## -mmmx: Open the MMX instruction to add code performance. See the CPU product manual to determine if the CPU contains the MMX function. Suitable for PentiumMMX compatible CPU. ## -msse: Open the SSE instruction to add code performance. See the CPU product manual to determine if the CPU contains the SSE function. Suitable for PentiumIII compatible CPU. ## -msse2: Open the SSE2 instruction to increase the code performance.

8. CCACHE CCache is a cache for program compilation, and speeds up compilation time by reducing the number of repeating code.
Installation process:
SU
CD / USR / PORTS / DEVEL / CCACHE /
Make Install Clean
CD / USR /
Mkdir ccache
CD / usr / sbin
Ln -s / usr / local / bin / ccache gcc
Ln -s / usr / local / bin / ccache cc
Ln -s / usr / local / bin / ccache c
Ln -s / usr / local / bin / ccache g
Ln -s / usr / local / bin / ccache cpp
Echo "Stenv ccache_dir / usr / ccache" >> /Root/.cshrc
REHASH
exit
Finally, you can view the current compilation status by running ccache -s. Ok, you can now CVSUP system code and ports tree. Still start building your FreeBSD 5?
