***Beta release software please treat it as such*** Net-Work Version 4.9á This little utility will send I/O to and from your file server at an alarming rate. To run it type Net-Work filename.dat where filename.dat is any output file name. When using it in a multi user environment please make sure that the file name given is different for each test station. Syntax for running Net?? filen NOTE : Output filename must NOT be longer than 6 letters also it may NOT have an extension Below is the Beta release history file, for those users who dont know how many hours of development goes into even the smallest of programs. Have fun Ian Gerada Centre Group Tel : +27-11-482-1040 (Voice) Disclaimer : All net?? versions are FREEWARE feel free to hand this file out to anyone. I Ian Gerada take no responsibility for any damage caused by this program whatsoever. If you would like to send a donation to me post it to the following address : Ian Gerada 14 Park Road Richmond Johannesburg 2008 South Africa Q&A : Q) Will Net?? work on a non Network Machine ? A) Yes however it wont prove anything except work your hard drive quite hard. Q) Will Net?? damage or delete data on my hard drive ? A) Net?? writes data just the way you would if you were copying files therefore no it wont. Q) Once I have run Net?? I find a whole lot (15) of strange files on my hard disk, what are these things ? A) These files are the output files created by Net?? feel free to delete them. Q) I keep getting "NOT ENOUGH FILE HANDLES" ? A) Put your FILES statement in your config.sys up to at least 15 History : October 18 1990 V4.9á Ok some great new features and a bug fix Net49 now includes speed specifications and a SHELL to dos, the shell may take a couple of seconds to execute but still it works. The 400 run time barrier FIXED, I will however be running it overnight tonight to see if the 16282 barrier has been fixed along with the 400 (Times run) barrier. Output file size has now been changed, (smaller now = 168 bytes) I will enlarge it later, to 4k which I believe is a typical packet size for many networks. October 17 1990 V4.8á After some wide area Official release testing we have decided to go back to beta versions until all problems are sorted out. Program still falling over after about 400 runs this will be sorted out in the next release. I have changed the output file from becoming to messy, to be piped into a directory (Same name as your output file) now once the code stops running you are left with one EMPTY subdirectory which you can then delete. I have decided for the meantime to leave that directory there in case any one wants to UNERASE the files and see what kind of output is being sent to them. October 01 1990 V1.01 WHEW !!! Made it Version 1.1 finally released first official release Enjoy chaps, lets hope your Networks stand up to the heavy load. September 27 1990 V4.7á Now opens and writes to 15 files. Even more % utilization on LAN I/O files are now 462 bytes each (*15) September 27 1990 V4.6á **IMPORTANT NOTICE IMPORTANT NOTICE** When specifying an output file it MUST be less than 6 letters long. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ With Version 4.6á Net?? opens and closed a total of 9 files instead of one, as the code progresses I will force it to open more. This will put up your Network utilization LIKE CRAZY Your output file has now dropped in size to 770 bytes (one or two of them may be 940 bytes) September 27 1990 V4.5á Added in a second icon (more cosmetic changes) I have not forgotten those who want to let this file run overnight, still have to sort out the 16282 barrier. September 26 1990 V4.4á Changed speed icon (cosmetic) oops forgot to display to screen PRESS Q to Quit ! fixed September 25 1990 V4.3á Renamed *.exe code to be Net??.Exe where ?? is the current version number. Put in a moving icon and colour this will give a visual representation of the workstation speed. Also added in ELAPSED TIME FOR LAST TEST, now FULLY multi user. Tested under Adv 2.15 Novell Netware from 15 workstations without a problem. A good tip here when running the code from every work station EG : Net43 Ian Give the name of the machine as an output file, from the server it will be interesting to see how fast each machine accesses the lan. Problem still to be sorted out is that after 16282 loops the program bombs out. Although the file server performance only goes up to +/- 40-80 % your disk write pending shoots up to about 30-40 sometimes higher. (This was on an IBM Model 80 machine. Official release Version 1.0 should be out within a month or so V4.2á Increased I/O file to be 7.238 k instead of 110 bytes the program is slower but it works your network harder. Still not 100 % multi user only two machines at once. Will fix this with next release. V4.1á [REWRITE - Also first Beta Release] Fixed up multi user problem allowing code to be executed from two workstations at once. V3.1å Network.tmp grew until it filled up hard drive fixed this problem Stack problem with multi nesting hopefully got this problem sorted out by defining stack to 32766 V2.1å First alpha release only pushed network to 11% utilization Had to fix this. V1.2å Code breaking up and re writing it's own source to Network drive ! problem fixed stack size problems V1.0å First release for alpha testers [In House version only] Code working however a bit raw with next release will have to beef up lan I/O
