Hi, please do turn off HTML in your mail program - use only plain text: Especially when mailing to the list, everybody otherwise gets TWO copies of the text (although only one mail, this is called "alternative" format), one in text and one in HTML. The HTML version marks every single line of text separately as being in Arial font etc.! If you use Outlook (which is crappy) you probably have to disable HTML mail for different address book entries separately or something.
Why did you use STACKS=9,256 - how about STACKS=0,0 ??? Interesting results... all caches 2 MB. LBAcache, SMARTDRV, SMARTDRV/WriteBack a) 9 MB of cache misses: 75 / 84 / 78 / 81 seconds for none / LBAcache / SMARTDRV / S.D.W.B. respectively b) copying 1.2 MB 10 times in a row: 69 / 79 / 49 / 81 seconds for the same candidates. So on this SCSI 386sx 20 MHz (31 MB FAT16, FreeDOS 2035-FAT16, FreeCOM XMS swap 12 MB RAM...) the overhead of cache misses for 2 MB cache size is 0.3 sec/MB smartdrv, 1 sec/MB LBAcache, 0.7 sec/MB smartdrv_with_writeback and the overhead for cache hits is ... 2.5 sec/MB higher with writeback or LBAcache than with plain SMARTDRV, strange! What does LBAcache STAT tell after each test? And SMARTDRV statistics? I hope at they did have lots of cache hits in the second test? In what way did you copy the same file 10 times? From harddisk to ramdisk? >From one directory to another one? I think for test b) you need a bigger LBAcache for that, something like THREE megabytes. Please try that (both LBAcache and the writeback feature of SMARTDRV store WRITTEN data in the cache. Therefore if you copy 1.2 MB disk -> disk, BOTH the source file and the target file will be stored in the cache!). (Hm, why are we discussing this on -kernel? Feels more like -devel...!?) Thanks for re-testing already ;-). Eric PS: If INTERLNK crashes FreeDOS, how about INTERSVR? And did it help to - load no HIMEM / EMM386 - use no XMS swapping FreeCOM - use no UMBs / do not load DOS to HMA - ...? You just wrote "various contents" for config sys - but to get started, an as fail-safe as possible config would be better. > Test 1: copy a specific group of files, about 9 MB > No disk cache: 1:15 > LBACACHE 2 MB: 1:24 > SMARTDRV 2 MB: 1:18 > SMARTDRV WC 2 MB: 1:21 > Test 2: copy the same file 10 times, the file was about 1.2 MB > No disk cache: 1:09 > LBACACHE 2 MB: 1:19 > SMARTDRV 2 MB: 0:49 > SMARTDRV WC 2 MB: 1:21 (WC = delayed write cache feature enabled) ------------------------------------------------------- This SF.Net email is sponsored by the new InstallShield X. >From Windows to Linux, servers to mobile, InstallShield X is the one installation-authoring solution that does it all.
