Thanks to everyone who helped me with opinions/tips on Hyperscript Tools -
Could not reply personally to some of them because my mailer refused to accept
certain address formats.

Well, we are still evaluating the development environment that Hyperscript
provides, but performance does not seem too much of an issue now. Though
it was too slow on a 386/33, now we have it installed on a Compaq Prolinea
4/33, and it runs quite fast. However, our target platform is a Sparc 10
Model 41, and the local Informix dealer doesn't seem aware of the status of
the X version(s). Has anybody out there used Hyperscript on Sparcs or knows
when it is due ?

I have not used Uniface, Gupta or PowerBuilder, but do these packages provide
you any way of buffering/caching data from the server in a local (on the
client) database in a user-controllable way ? At an exhibition, I had seen
a university research product that used to deliver amazing performance with
an Acer 486 client and a Unisys server by automatically tuning the prefetch.
It relied on linking the application with some libraries that provided access
prediction.

Greetings.

HyperScript Tools has been on SPARC (SunOS 4.1.3 and Solaris 2.2) since
last year.  I have (and enjoy) both platforms.  Performance is
better on a SPARC IPX than a 486DX33 - both running 16 or 32 Mb RAM.

The only complaint for the UNIX ports is the lack of a multithreaded
kernel in HyperScript - maybe one day.

One key issue for your environment may be seamless cross platform
portability - this is a strong suit for HyperScript, it's shipped with
a porting and deployment guide which basically says that the code
doesn't need ANY changes.  Font metrics, aspect ratio and so on remain
a pain when moving from something nice (read UNIX) to somewhere
barren (read windows/DOS PC - blecch!) but Mr Informix recognises the
proliferation of the PC Windows market and products are developed
accordingly.

HyperScript has built in ANSI SQL with Informix extensions.  There's
a handful of local caching and buffering and data storage/massage
techniques which yield impressive throughput and efficiency from the
client.  As for 'access prediction' - sounds very shiney, tell me,
does the client do SQL optimisation before the server, then do its
own caching?  I've been writing client/server applications in HyperSript
for a few years now and every now and then you hear some ripping 'throw
away' lines like 'access prediction' or 'optimistic locking' or
'reading the chicken bones' and they all boil down to much the same;
tripe.  As for 'amazing performance', Informix will invite any
opportunity to do comparative bench tests - give your local guy
a call, way some money in his face, and suggest a trial exercise.

Seriously, though, your local rep should know about the platforms
for HyperScript.

Also, your mailer addressing problems are probably just syntax; if

maybe you already know all this, just trying to help.
