Hi all,

Before maybe migrating to 64 bits, has anyone noticed any speed advantages or disadvantages when running as 64 bit?

regards,

MiguelL

Hi Miguel;

  I've had my STD Framework & derived Apps from that framework running in 64 bit mode since PB 12.6. I have not noticed any appreciable speed difference. I have noticed that 64 bit apps take a longer time to instantiate (get started). However once that aspect has completed, they seem to run the same as 32 bit P-Code. Of course, M-Code is a different matter but PB only supports 32 bit execution in M-Code compiled Apps.

   I have certainly noticed that 64 bit Apps handle 64 bit DB drivers a little faster & of course, large result sets due to improved address space allocation by the O/S. That then translated into little or no App crashes due to the old 4G address space limitation of 32 bit Apps.

HTH

Regards ... Chris

Thank you Chris,

That's great information. So, for us, no rush, though I will try and convert in a future. I know about the advantage when retrieving big data sets, so it could give us some speed improvemnts, but for now we haven't had a single problem for over 15 years with our 32 bit applications.

A part from that, we do have one customer who needs 32 bit, as they use some kind of "terminal thingies" which are 32 bit. I don't know the exact name of it.

regards,

MiguelL

I find that "thingies" are usually always important... LOL!
