I have
actually been doing a fair it of reading on this since the topic was brought up, and stand corrected, as earlier mentioned. But I have to say guys that NT is still fairly "pants" when it comes to handling multi threaded processes.. Win2K is a great improvement but M$ still has a lot of work to do on in my view. (only when you compare this against UNIX)

Now
don't get me wrong, there is enough traffic on this list about this at the moment, so I dont want more bandwith added with this thread if at all possible :)

Thanks
for the reply anyway Yong, I think I will wait for a "good" book on Win2k to come out (unless you know one?) before I go out and buy one (books come out of my pocket as I am a sales person mostly).. NT as far as I am concerned is now in Win2K's shadow, and I think that is the way of the future for Windowze bound people.

For
all out there that have used NT and not Win2K - TRY IT.. Services are handled a LOT better, file management and sharing.. All sorts of new fun stuff to sink your teeth in to..

As a
side note, for the last line of my first paragraph - I also feel that UNIX cannot be compared in anyway to Windows at this time. Windowze O/S's are designed for pointy clicky people that prefer to look at a nice GUI interface, and generally don't have the indepth technical knowledge that a good UNIX sys admin does..

(If
there any NT admins out there don't flame me, I have to deal with it every day of my life...)

The
views expressed here are soley those coming out of my coffee deprived hungover mind.. They do not express those of my employers, though I'm sure they agree :^)

  Hi, Mark,
  Async I/O is available on Windows, at least NT. It's not an   easy topic. If you think you already know enough about   operating systems in general, I suggest you read David   Solomon's "Inside WindowsNT". For a lab test, launch Performance   Monitor on your NT box and look at the counters for   Cache.
  I'm not sure by "single thread management" whether you mean NT   can't have multiple processes or Oracle on NT runs as   one thread. The former is obviously wrong. The latter   is a design issue inside Oracle Corporation and the question <FONT   size=2>as to why was asked on this forum before without an answer (without an   answer I can remember, that is).

  Asynch I/O on a Windowze box? supresses a snigger...   

  To the best of my knowledge there are no Windows based system   that can take advantage of this, single thread   management can be enough a problem sometimes..   

  But, I may be wrong.. List?
