Yesterday, thru Central Coast Software's BBS connection, I upgraded my version of QuarterBack tools to the latest version (1.3c, December 6, 1990). I was/am hoping that the bugs reported in previous versions had been eradicated, so I went out and tested it. My configuration is a B2000, revision 4.3 motherboard, 512K Agnus, A2052 memory card w/2 meg), GVP series II HardCard (w/ram installed - 2meg), Supra 2400ZI internal modem. Software is Kickstart 34.5, Workbench 34.28 (Technically, AmigaDos 1.3.2), ConMan 1.3e, ArpShell, Dmouse 1.25. First thing I did was back up my partitions (one can never be too safe!), then ran the tools program against both partitions, making sure to re-boot after each partition was completed (Oh yes, I shut down BlitzDisk II and VirusX 4.01 as a precaution *before* I started). Afterward, I ran the DH0: partiton thru DiskSpeed 3.1 and came up with: DiskSpeed 3.1 - Copyright (c) 1989,90 by MKSoft Development Device: Drive0: Comment CPI-3100, 68000 mode, medium (w/BlitzDisk II) Test Intensity: Med Performance Stress: None 12 Files/s Create 64 Files/s Open/Close 205 Files/s Scan 54 Files/s Delete 189 Seek/Read Buffer Size 512 4096 32768 262144 --------- --------- --------- --------- --------- Bytes/s Create 27380 118514 228067 308546 Bytes/s Write 28558 170977 425412 596523 Bytes/s Read 143318 280106 539388 657930 I then realized that I had run the test with BlitzDisk running, so I shut down BD and ran the speed test again. Results: DiskSpeed 3.1 - Copyright (c) 1989,90 by MKSoft Development Device: Drive0: Comment CPI-3100, 68000 mode, medium (no BlitzDisk II) Test Intensity: Med Performance Stress: None 10 Files/s Create 21 Files/s Open/Close 104 Files/s Scan 25 Files/s Delete 189 Seek/Read Buffer Size 512 4096 32768 262144 --------- --------- --------- --------- --------- Bytes/s Create 28049 142708 244922 308546 Bytes/s Write 29188 180825 522247 617093 Bytes/s Read 61003 275601 520223 625237 Now from previous testing, I had the drive running in the 350K to 400K range, so I would say that reorganization did a pretty damn good job of increasing disk throughput, even though some of the read counts may have been skewed because of my running of BlitzDisk.
