TC9 randomly starts using an abnormal amount of CPU cycles after idling.

I ran a performance counter on TC9 while simply writing some code in the editor, nothing else. Check the attached graph. In addition to high CPU usage while moving the mouse around, it seems CPU usage  jumps to 100% everytime I hit a key. I suppose this is from the syntax checker verifying on KeyPress events. That should be done in a separate thread and on a timer. There is no point in verifying if the syntax is good before I finished typing an expression. Once every 5 seconds would be plenty for me.

Any comments on these issues?

While most of the performance issues seem to be gone with build 9.10, one remains.



Every time I type a character in any editor window of TC9, CPU usage goes to 100% for at least 1-2 seconds. Fortunately duration does not "stack", but I find it quite bizarre to analyze the contents of a script file at every single keypress.



As noted above, if this is the syntax checker, it should be checking once every N seconds, on a timer. Checking every keypress makes for very poor response time while typing code. In some instances, holding Shift gets delayed because of this.



For example:

While typing some sentence or code, try inserting a Cap Somewhere in there.



If I were to type this normally in the TC9 editor, sometimes it would come out as:

While typing some sentence or code, try inserting a cAP somEWHere in there.



I am working on a VM with only one vCPU, so maybe that has something to do with it, however putting anything longer than 1-2 lines of code in a keypress event is a big no-no in any case.

Any input on this? I posted the original comment  almost a full month ago...

Is Smartbear purposedly avoiding to answer this question? I would like to have the official word on this issue. Seeing as it was posted over a month ago, I think ample time was given to investigate the issue and open a ticket if need be.

I can confirm it is not auto-completion, as I have it permanently disabled, since it does not work half the time and takes forever to show up.



As I stated above, I am pretty sure this is the IDE checking syntax every keypress.
