Zeoslib Portal

Hello,

I wanted to ask if ZeosLib have a problem with APIs (visual controls) Windows 7 and 8 64-bit?

Since it is the following:

When I generate any application that has the DBGrid (connected with ZQuery and DataSource) to navigate the DBGrid is slow (as if you were processing something), but occurs only if I keep the mouse cursor over the DBGrid this when processing the SQL, this happened in version 6.6.6 and now continues the same problem in version 7.1.2. I did a test with UniDAC Devart component of this problem occurred and not stay slow.

Has some configuration I can do for my application to be totally compatible?

Has anyone experienced this or know how I can fix this?

I use Delphi 7.0 (Build 4453) Enterprise Windows 7 Professional 64 Bit.

Note: The same ZeosLib application running on Windows XP 32 bit or Windows 7 32-bit is not the problem.


I thank you.

Nope no idea. Have to pass. Just a hint if you want to get real performance swith to 7.2 from SVN.

Do you use SQLHourGlass option?

Hello, EgonHugeist.

This same problem was in the SQLHourGlass ZConnection. Another post I saw here in the forum. I put "False" on SQLHourGlass property and did not occur more slowly.

So this is the SQLHourGlass is "True" to run on Windows 64-bit slow.

In the new version 7.2 was corrected using SQLHourGlass?

Thank you very much.

I don't know anything about real performance issues related to 32/64Bit targets. AFAIK is FB a bit slower but more i can't say. There is virtually no real (except some integer/pointer declarations) between these compile targets.
