- : Well, an RS/6000 is slightly different than an Intel architecture. On
- : top of which, you don't have to worry about 64K DMA boundaries. Further,
- : compare the price of an RS/6000 to a 386 machine. Something like
- : $60,000+ to $3,000??
-
- : I think a more interesting comparison would be between a 386 *nix like
- : Linux or 386BSD and Coherent. Could you do that maybe?
-
- I could if I had the things. I did it on every system I have access to,
- and the only notable ones were AIX and Coherent. (SCO Xenix allows
- 60 files open per process, at least on the systems we have at work.)
- My original posting contained the program, so if someone else wants
- to know how it runs on their system all they had to do is compile it
- and try.
-
- I wish someone would comment on the point I was trying to make, though!!!!!!
- Which was.... that Coherent 's creat and open routines STILL CREATE THE
- FILE EVEN THOUGH THEY RETURN AN ERROR CODE.
-
- Even when someone from MWC responded all they said was that the next
- version would allow 60 files. I could not get any comment at all on
- the obvious B U G in the system.
-
- don't get me wrong--I LIKE Coherent and I'll continue to use it in the
- forseeable future. That's why I feel compelled to point out bugs when I
- see 'em so they can get fixed. It would make me, as a developer, feel
- better however if MWC would acknowledge them when they are reported.
