Hi again,
Here's more LBACACHE test results along with SMARTDRV comparisons. Maybe
more tests will be done later.
CONFIG.SYS contents:
DEVICE=C:\DOS\FDXXMS.SYS
DOS=HIGH
FILES=20
BUFFERS=20
STACKS=0,0
LASTDRIVE=E
AUTOEXEC.BAT contents:
@ECHO OFF
PATH=C:\DOS
(disk cache command)
Test 1, a 1.2 MB file copied 10 times (same as last time):
No disk cache: 1:10
LBACACHE 3 MB, 1:10
SMARTDRV 3 MB, 0:48
SMARTDRV WC 3 MB, 0:50
LBACACHE 8 MB, 1:11
LBACACHE 11 MB, 1:07
SMARTDRV 11 MB, 0:52
SMARTDRV WC 11 MB, 0:16
LBACACHE 256 KB, 1:13
LBACACHE 512 KB, 1:14
SMARTDRV 512 KB, 1:11
Info samples (edited for easy reading):
LBACACHE 3 MB
XMS handle has size (in kB) 00003072
read hits: 00010802 read misses: 00010867
write hits: 00000087 write misses: 00021664
sectors per bin in table: 0016 bytes per bin in table: 0008
*** kilo-reads: 0021 --> percentage of hits: 0049
*** kilo-writes: 0021 --> percentage of hits: 0000
SMARTDRV 3 MB
Room for 384 elements of 8,192 bytes each
There have been 1,493 cache hits
and 1,690 cache misses
SMARTDRV WC 3 MB
Room for 384 elements of 8,192 bytes each
There have been 1,762 cache hits
and 1,508 cache misses
Hope it all makes sense,
Justin
