O$ 5.2.3: runtime slow after unicode conversion from O$ 4.3

[Stephane Pras]

Nick,

I experienced the same kind of problem, but running Omnis Studio 4.3.2.1
(non-unicode) on Mac OS X 10.11.6. It fully disappeared after upgrading to
Omnis Studio 5.2.3 (unicode).

It seems to be related to a slower dialog between software and OS X when one
is non-unicode and the other one unicode, probably because of some
unicode/non-unicode translation needs. This is particularly obvious when
printing reports, which become tremendously long.

Should be resolved if everybody is unicode, or everybody is non-unicode.

Subject:  O$ 5.2.3: runtime slow after unicode conversion from O$ 4.3

Hi,

We recently updated our Omnis Studio 4.3.2.1 non-unicode library to
Omnis Studio 5.2.3 (unicode). We didn't need to make any changes to
the library's code as we had already made all the necessary
preparations in Studio 4.

The library is now run on the same machines as before (most of which
are running MacOS 10.8.5), only now they are using the Omnis Studio
5.2.3 runtime. We connect to the same ODB and Postgres databases
as before.

But for some reason, the library (or rather the runtime) slows down
after some time using it. It feels like there is some memory leak
causing it, because when you quit the application and relaunch,
everything is back OK.

Does anybody have a similar experience? Any clue what might be
causing this?

My first thought was: object instances. We use a bunch of them, but
had no performance issues in Studio 4. Has anything changed between
Studio 4 and 5 on how objects are handled?

My second thought was: externals. Again, we use a bunch of them, and
obviously they are not exactly the same (unicode vs non-unicode).
But my tests don't show any performance decreases when I only use
the externals.


Best regards,

Nick Renders
