[Freedos-user] For Eric - NWCACHE write caching test results; and a new problem
There's good news and there's bad news. The good news is that, as you expected, there's only a small difference between a big write cache with a long delay and a small write cache with a short delay. The bad news is that I found some big performance problems (in reading and deleting files) that exist in FreeDOS but not in DRDOS 7.03. Caching (particularly write-caching) helps both OSs but it helps DRDOS a lot more. E.g. FreeDOS takes 50 seconds to read and delete ~300 files. DRDOS does the same task in 6 seconds. I don't know why. Here are the details: First the cache test results. I ran UKA17X2 with NWCACHE configured four different ways. I rebooted between tests. Also I used newly created subdirectories for each test. Running UKA17X2 (end time - start time) on FreeDOS ca. 2006/08/20 - with write caching -- 14 sec nwcache 6144 6144 /lend=off /bl=16 /delay=333 /w=64 11 sec nwcache 6144 6144 /lend=off /bl=16 /delay=333 /w=6144 14 sec nwcache 6144 6144 /lend=off /bl=16 /delay=5000 /w=64 11 sec nwcache 6144 6144 /lend=off /bl=16 /delay=5000 /w=6144 14 sec smartdrv (no operands - default is write caching for hdds) without write caching - 40 sec smartdrv c (read caching on but write caching off for c:) 9 secno cache - target directory was on a ramdisk In the with write caching results, the difference between 11 seconds and 14 seconds is less significant than it appears. That measurement is based on the difference between the time on the DOS prompt when the cmd is executed and the time on the DOS prompt when the cmd ends. (I allowed for the time required to type the cmd too. I typed an invalid form of the cmd first and entered it. Then I recalled that cmd, corrected the one char that made it invalid, and then pressed enter. I allowed one second for that recall and correction process.) The problem is the ending time on the DOS prompt. The DOS prompt returns before the cache finishes writing. I know this because the hdd LED is still flashing for about 3 seconds or so after the DOS prompt appears. That DOS prompt is useless until the cache finishes writing; but its premature arrival distorts the time readings in these tests. I haven't tested LBACACHE yet. I had planned to but I found another problem that seemed more important. FWIW, I would expect that LBACACHE's lack of write caching capability will put its performance in the same ballpark as SMARTDRV or NWCACHE when they have write caching disabled. From the tests that I *did* complete, the numbers suggest that the size of the write cache is more significant than the delay. But the difference is not big and, as I pointed out with the premature return of the DOS prompt, that difference may really be even smaller than these numbers indicate. The biggest difference is between *any* write caching and *no* write caching at all. Now for the bad news: When I started deleting the files created in the above tests, the performance was awful. It took longer to delete the files than it took to create them. Of course I was doing a little more than just deleting those files (the pgm that I used also read each file before deleting it). But AFAIK that was nothing that should have caused the performance to deteriorate that badly. Here are some of the timing numbers for deleting a single tree: 50 seconds With smartdrv write caching on 80 seconds With nwcache read caching on 100 seconds With no cache at all Remember that most of these trees were created in under 15 seconds. The idea that it would take 3x longer to read and delete a file than it took to create and write that file seems wrong. In addition, while each tree was being read and deleted, FreeDOS abused the disk (with constant, drive-chattering, seeks) during the entire deletion process. I suspect that the disk was seeking so much because, for each file, it was doing the following: 1) Reading from one subdirectory cluster a) maybe reading another non-contiguous, subdirectory cluster b) maybe reading a third non-contiguous, subdirectory cluster 2) reading the FAT to find out which secondary clusters that file occupied 3) reading all the file's clusters 4) Writing in one of the subdirectory's (non-contiguous) clusters again (to the delete the directory entry) 5) Writing to the first FAT (to mark the file's clusters as free); 6) Writing to the second FAT (to mark the file's clusters as free); Multiply that process by ~300 files. This process seems like it *should* benefit greatly from write caching. Yet, even when write caching

Re: [Freedos-user] Problem with FD-KEYB 2.0 final
Many thanks, Diego. It is, then, a known problem (ocurred in last version too, but doesn't seem to arise under MS-DOS or NTVDM, so as you say the problem may be in FreeCOM). I would like to investigate into that too, although I just wanted to clean up some missing bugs in KEYB itself before proceed. Of course, I may possibly have introduced new bugs, but it is for sure that KEYB 2.0 has a critical bug (for Strings) less than pre-4 had. Anyway thanks for the report, I'll keep an eye on that too. Just for a hint for current FreeCOM developers, KEYB loads layouts into an internal heap of itself (for historical reasons it is again a bunch of 0's, but that does NOT make sense anymore since pre3, will change that too), then once I know the size of the Layout I reserve a MCB into UMB (change the MCB allocation policy, and then restore it), unless you use /NOHI. I place the layout there (a KeybCB), and then I cut the KEYB.EXE MCB to the minimum and Terminate and Stay Resident. That memory is never written to for the moment, in fact the only writes to memory in KEYB are very few variables (such as combi pending, or perhaps the secondary buffer: all of them reside in KEYB's MCB during the whole history of KEYB.
