Hi, I ran UNIX bench on 4 of our machines. The results are below. What is strange is that 2.2 makes better than 2.4! Is it a known fact? And is the UNIX bench better with 2 CPU? -jec Results: Host1: 2xPIII 550MHz / 1Gb RAM / RAID5 SCSI / 2.4.6smp + LVM Result: 164.7 Host2: 2xPIII 866MHz / 1Gb RAM / RAID1 soft IDE / 2.4.16smp + LVM Result: 195.7 Host3: 1xPIII 800MHz / 512Mb RAM / IDE / 2.2.19 RedHat 6.2 Result: 208.6 Host4: 1xPIII 600MHz / 256Mb RAM / IDE / 2.4.19-pre2-ac4-preempt Result: 153.6 Host1: Dhrystone 2 using register variables 116700.0 1139475.0 97.6 Double-Precision Whetstone 55.0 295.2 53.7 Execl Throughput 43.0 697.7 162.3 File Copy 1024 bufsize 2000 maxblocks 3960.0 83438.0 210.7 File Copy 256 bufsize 500 maxblocks 1655.0 38613.0 233.3 File Copy 4096 bufsize 8000 maxblocks 5800.0 121259.0 209.1 Pipe Throughput 12440.0 254518.7 204.6 Process Creation 126.0 1831.7 145.4 Shell Scripts (8 concurrent) 6.0 201.7 336.2 System Call Overhead 15000.0 251716.1 167.8 ========= FINAL SCORE 164.7 Host2: Dhrystone 2 using register variables 116700.0 1837005.3 157.4 Double-Precision Whetstone 55.0 478.4 87.0 Execl Throughput 43.0 923.8 214.8 File Copy 1024 bufsize 2000 maxblocks 3960.0 54663.0 138.0 File Copy 256 bufsize 500 maxblocks 1655.0 18601.0 112.4 File Copy 4096 bufsize 8000 maxblocks 5800.0 96807.0 166.9 Pipe Throughput 12440.0 399294.5 321.0 Process Creation 126.0 3503.8 278.1 Shell Scripts (8 concurrent) 6.0 277.0 461.7 System Call Overhead 15000.0 393738.7 262.5 ========= FINAL SCORE 195.7 Host3: Dhrystone 2 using register variables 116700.0 1506306.9 129.1 Double-Precision Whetstone 55.0 364.4 66.3 Execl Throughput 43.0 1103.3 256.6 File Copy 1024 bufsize 2000 maxblocks 3960.0 110403.0 278.8 File Copy 256 bufsize 500 maxblocks 1655.0 53065.0 320.6 File Copy 4096 bufsize 8000 maxblocks 5800.0 151107.0 260.5 Pipe Throughput 12440.0 378679.6 304.4 Pipe-based Context Switching 4000.0 161272.9 403.2 Process Creation 126.0 7144.7 567.0 Shell Scripts (8 concurrent) 6.0 20.0 33.3 System Call Overhead 15000.0 412399.5 274.9 ========= FINAL SCORE 208.6 Host4: Dhrystone 2 using register variables 116700.0 1099714.7 94.2 Double-Precision Whetstone 55.0 328.1 59.7 Execl Throughput 43.0 692.1 161.0 File Copy 1024 bufsize 2000 maxblocks 3960.0 56029.0 141.5 File Copy 256 bufsize 500 maxblocks 1655.0 18783.0 113.5 File Copy 4096 bufsize 8000 maxblocks 5800.0 96243.0 165.9 Pipe Throughput 12440.0 306228.7 246.2 Process Creation 126.0 3937.3 312.5 Shell Scripts (8 concurrent) 6.0 125.9 209.8 System Call Overhead 15000.0 282470.2 188.3 ========= FINAL SCORE 153.6 -- Jean-Eric Cuendet Linkvest SA Av des Baumettes 19, 1020 Renens Switzerland Tel +41 21 632 9043 Fax +41 21 632 9090 E-mail: jean-eric.cuendet@linkvest.com http://www.linkvest.com -------------------------------------------------------- - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
