인텔의 개발샘플 완제품

모든 테스트는 disk io가 거의 영향을 끼치지 못하도록 tmpfs위에서 실행되었습니다.

OS는 다음과 같이 설정되었습니다.

배포판: Gentoo Linux 1.4
커널 : linux-2.6.1-mm1
gcc: 3.3.2 20031218_branch
glibc 2.3.3 20031222_snapshot
pentium4 시스템은 hyperthread가 enable되었습니다. 즉 SMP로 동작합니다.

시스템 빌드에 사용한 CFLAGS는 다음과 같습니다.

barton: "-pipe -march=athlon-xp -O3 -mfpmath=sse" 
prescot: "-pipe -march=pentium4 -O3 -mfpmath=sse"

pystone: python의 연산처리를 비교하는 벤치마크입니다.

barton shm #  python /usr/lib/python2.3/test/pystone.py 
Pystone(1.1) time for 50000 passes = 1.35 
This machine benchmarks at 37037 pystones/second

prescot shm # python /usr/lib/python2.3/test/pystone.py 
Pystone(1.1) time for 50000 passes = 1.67 
This machine benchmarks at 29940.1 pystones/second

ffmpeg: 각종 비디오 포맷을 인코딩/디코딩해주는 프로그램입니다. msmpeg 포맷을 wmv형식으로 변환해보았습니다.

linux kernel build (2.6.1-mm1)

커널빌드는 cpu성능보다는 디스크 io에 따라 많은 차이가 난다. 하지만 diskio가 느릴꺼라고 생각했던 barton시스템이 더 빠른 수치가 나왔다.

barton linux-2.6.1-mm1 # time make -j2 oldconfig bzImage 
... 
real    4m5.999s 
user    3m41.998s 
sys     0m22.507s

prescot linux-2.6.1-mm1 # time make -j2 oldconfig bzImage 
... 
real    4m58.875s 
user    4m30.871s 
sys     0m30.507s

참고로 diskio는 다음과 같다.

barton linux-2.6.1-mm1 # hdparm -t /dev/hda 
  
/dev/hda: 
 Timing buffered disk reads:   76 MB in  3.01 seconds =  25.27 MB/sec

prescot linux-2.6.1-mm1 # hdparm -t /dev/sda 
  
/dev/sda: 
 Timing buffered disk reads:  168 MB in  3.03 seconds =  55.44 MB/sec
