I tested it on P4 2.8GHz and P3 600MHz
with "SQLTools 1.4.1 Beta build 66".
1. Start SQLTools, don't connect.
2. Run 'Task manager'.
Watch Processes and CPU usage (now is 0%?).
3. Create for example 6 tabs.
On P4 minimized SQLTools use 3-5% of CPU,
on P3 6-10%. But it doesn't do anything!
This behaviour doesn't exist in OpenEditor.
