Setting PhraseExpander to high priority

In rare situations, PhraseExpander may briefly stop responding for a short time, typically on systems that are under heavy load. These short interruptions usually resolve on their own and do not indicate a malfunction.

Some users have noticed that increasing the application’s priority in Windows can improve responsiveness in these specific cases.

Windows uses a scheduler to decide which running applications get CPU time. When the system is busy (for example, due to browsers, security software, or other background processes), applications running at normal priority may receive CPU time less frequently. If PhraseExpander needs to process text expansions or macros at that moment, this can lead to brief delays and the impression that the application is not responding.

Raising the process priority tells Windows to schedule PhraseExpander more aggressively, reducing these delays. While this can improve responsiveness, it is usually a workaround rather than a permanent solution. Optimizing system load and ensuring PhraseExpander can run without heavy competition for CPU resources will generally lead to the best experience.

Modify the application's priority only if you are experiencing issues with PhraseExpander.
