Why is Notepad++ so slow on large files now?

poweradminllc

I’ve been using Notepad++ to look at 200MB+ log files for years. A few months back I switched to the 64-bit version which allowed looking at multiple 300MB+ files at a time which is great. A few weeks ago(?) there was an update, and now just opening such a file is taking probably 20 seconds or more.

I’ve removed all plugins except for the Plugin Manager and NppSaveAsAdmin, but it hasn’t helped. What is going on internally that it is so much slower now? Is there some setting I can change?

Thanks
Doug

@poweradminllc ,

What is your slow-working Notepad++ version?

I have met a same ‘slowness’ problem and solved it.
So I just place simple comment.
Do not take it seriously.

@pnedev, yes that would help wouldn’t it. 7.5.9 (64-bit). I usually stay on the latest release.

Do you use line wrapping, line hiding or code folding?

If yes, there has been introduced a regression in v7.5.9 that causes a severe performance decrease if one of the features above is used.

You could download the last AppVeyor build of v7.5.9 that doesn’t include the changes regarding plugin hosting of v7.6. You could also update to v7.6.1, the latest release. But be warned - you will run into trouble with your plugins, none of them will be available and some even may not work after you have done all required changes.

To download the patched v7.5.9 follow the link above and click on Notepad++.X64.Unicode Release.exe. If this doesn’t work for you go to this page and click on Notepad++.X64.Unicode Debug.exe.
