ADS causes very very slow system reaction while taskbar popup window displays over the ADS main window

by Nov 4, 2014

ADS always causes high CPU usage under the following scenario:

  1. Update ATI Mobility Radeon HD 3400 display driver version to 8.970.100.3000;
  2. Open ADS v10 and maximize the main window;
  3. Click the “3 Windows Explorer” icon (or any others) on the taskbar to display a popup window over the ADS main window;

then the Windows reacts very very slow to the mouse movement — the taskmgr shows that ADS uses many CPU slices.

All goes normal as soon as the popup window closes or disappears.

Thanks for your help.

Hi David,

1) You can try upgrading to ADS v13 to see if that resolves your issue

2) You might be seeing high CPU usage due to a low amount of free physical memory on your system which in turn causes the OS to do a lot of page swapping which causes CPU spikes

If neither of the above resolve your issue, please send us your Full Support information (Help -> About Aqua Data Studio), output of running “dxdiag” and all logs from your [USER_HOME]\.datastudio\logs directory.

You may either attach the above requested information to this thread or email us at

Hi Sachin,

1)I can’t download ADS v13, for it requires contacting the sales team;

2)The memory is sufficient: 4GB physical, 3GB recognized by WinXP 32bit, less than 1.5GB memory usage.

I’ve downgraded the ATI display driver to version 8.771.0.0, and now the ADS works fine.

I will soon attach the dxdiag info and ADS logs, after upgrading the driver to version 8.970.100.3000 later.

Hi David,

Please also attach your Help -> Support Information.

In addition, you may try disabling charts in ADS by:

File->Options->General->Charts->[Support Charts] = Disabled
File->Options->General->Chart->[Offscreen Rendering] = Disabled

Hi Sachin,

1)Now the ATI display driver version is 8.970.100.3000.
2)[Support Charts] already set to “Disabled” long time ago;
3)[Offscreen Rendering] = Defalut. Just changed to “Disabled” but the problem still exists.
