Excessive slowness for some users

We're getting a worrying number of reports of Audacity 3.x being
excessively slow for some users. The common factor being that the projects
are longer than about 30 minutes.

Most of the reports have been on Windows, but so are most of our users, so
that may not be significant.

On Linux, when working with project of an hour or more I have also
experienced some long waits, especially when closing the project (though  I
rarely work on projects that are more than a few minutes long).

A peculiarity is that the slowness may not appear immediately. It seems to
happen after working on the project for a while, and may be related to
using "Undo".

Below is the latest report that came in a few minutes ago.

I appreciate the work you do and you making it available free to the user.
It has helped me for years.



I do not want to complain but I am having some issues that I feel you
should be made aware of.



I am using a Windows 10 Computer. All of my recordings are voice only and
range from 30 to 60 minutes. Over the years I have made many recording
using audacity. I average 2-3 recordings a week and have used audacity
since one of your earliest versions.



A few weeks ago I upgraded to Audacity 3.0. With great expectation, I
loaded it, expecting my “wait” time to be reduced. The reverse happened on
nearly everything I do. It was so bad, I went back to my older version.
Today, I saw 3.02 was out and downloaded it. I recorded a 48 minute audio
without issue. However, When it came to editing, it was a different story.
Below are a few of the “wait times” I experienced.



·        Sound Finder took a long time but I did not time it.

·        Label Audio Split took over 20 minutes

·        Compressor took over 40 minutes.

·        Truncate Silence took a long time.

·        Saving the file also took an extremely long time.

·        Closing Audacity took over 21 minutes.

I hope this information helps resolve some issues. If I can be of help in
evaluating, I would be happy to do so.



Sincerely,

[redacted]
