This is kind of a dumb question but what is happening with
SCO UNIX 3.2 platform?
Is the development system out?
What do the owners think of the price/perfomance ratio?
How many users are on your SCO UNIX system?
Do they all use the X-windows that comes with it?
Now that ATT and Sun is going to release UNIX 4.0 real soon is
SCO going to have a 4.0 release?
Does Codeview work with the PCC compiler?
Is the fast file system the same as ISC's?
A related question is how would you benchmark the two?

I used to run C News on Interactive 386 and now I am running Xenix/386 with B News. I think C News would be much better with busy machine because this allow to run full news batch on specific time (C News' rnews just move batch to in-comming file directory). If you still want B News or any News software, I suggest to get newsfeed during night time. B News's rnews will push Xenix down on performance but I think there will be more problem with new SCO Unix and I will install C News instead of B News. I have tested SCO Unix in separate machine and I plan to move this into busy BBS machine. My opinion is that SCO Unix is not for everyone. I take this because I have alot of experience with System V on the job and I feel more comfortable with this than Xenix. Xenix is not a true System V but this is alot lighter than real System V on saving disk and memory spaces. For SCO Unix, I am not happy with SCO adding more files that I don't really need like MMDF mail, Security, extra copies of inittab files etc. I recommend SCO to offer two version: full and lite version. As far as I am awared, SCO Unix is better with modem than Xenix, especially autobauds on Unix while Xenix needs break signals. I heard many reports that SCO Unix can not run over 9600 bauds but I did many testing with Telebit with 19200 bauds without any problem. I will keep post with you on installing News in SCO Unix. willy -- %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % Willy Paine BBS/FAX +1-206-822-4615 % % willyp@seaeast.WA.COM FidoNet 1:343/15 % % uunet!nwnexus!seaeast!willyp fungus.dnet.dec.com!paine % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% % It takes less time to do a thing right than to explain % % why you did it wrong - Longfellow. % %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

Please do. SCO Unix is in my plans - maybe this summer but running 4 high speed modems (all locked) is a must (on a dumb card). Larry

Get C News + the various speedups and NICE changes I've done >and you don't even notice when news is running. Sorry, you missed the point here. I wrote the article about there being a problem on SCO UNIX when news was running. The point was not that news was a problem undex UNIX, the point was that anything that is extremely disk intensive causes a problem. You only solve a small part of the problem by making news more efficient. What happens when someone is running a cpio pipeline through compress? This also slows my SCO UNIX system down to a standstill. Sure, it also slowed the Xenix system, but the slowdown was much less with SCO XENIX 2.3. Unfortunately, I do not have numbers for you, all I have is the impressions I get while trying to get work done. Another interesting thing I have seen is with XENIX, even when my disk was extremely busy the disk activity light would flash. Now with UNIX, it stays on for seconds to minutes at a time. BTW: I jacked the number of disk buffers up to 2048 from 600 and it helped some, but not much. I have 8MB of memory in the system, so it is still not swapping. -- Terry Hull Department of Electrical and Computer Engineering, Kansas State University Work: terry@eecea.eece.ksu.edu, rutgers!ksuvax1!eecea!terry Play: terry@tah386.manhattan.ks.us, rutgers!ksuvax1!eecea!tah386!terry

Then a better version of news will help to some extent since it copies things around less. If you can't improve your system (with, for example, a new disk or controller) then the best thing I've found is to put in some sleep(1) calls. You can spread i/o to the point where it's a just a blip here and there vs a steady work stopping burst. -- Jon Zeeff <zeeff@b-tech.ann-arbor.mi.us> Branch Technology <zeeff@b-tech.mi.org> It's 1989.
