I am using RedHat in my office and I am handling large text files with kwrite. Now I am having this problem that the performance is somehow disappearing. Whereas it could easily handle the files once I got the machine it seems now that it gets easily stuck.

I usually have two kwrites open and copy and paste data from one file to another. The second kwrite seems to get stuck all the time, in scrolling the file, selecting and deleting and of course when pasting the data into it. It can easily take minutes before it starts responding.
The cpu goes to 100% for kwrite process when that happens.

I wonder if there is some cache or something that is now full and what I can do.

What is your hardware and which version of Kwrite are you using? I assume you have KDE is that right?

It is interesting to remember text is usually a light thing but when it come into font usage and if your CPU have to process many different ones, then the picture can change.

I'll check on the version, the machine is with 12 cores and plenty of RAM, but all of this is somewhat besides the point. Some time ago it was running fine - now it has taken a habit of getting stuck for minutes when I open two files, do copy paste between them or sometimes even just scroll the second one...So it is not as if the machine would lack the performance, it is that something is happening that steals that performance.

Sometimes in terminal I get QCliboard: timed out while waiting message...

Maybe emptying the clipboard from klipper or reducing the size of history could be a solution, maybe it is saving too many actions for undo...

I do not use Krite anymore and i cant remember if it is possible to change those settings but if it is possible reduce the number of undo to see what happen. Watch the process to see the mem usage too, might give some clues.
