exporting is slower than before

Hello,

i notice with the same computer, the mac mini M1 16go ram, exporting in mp4 is slower on premiere 22.0 and 22.1.0 than the 15.4.1 version. I did many times with differents edits and everytime is the same.

For example a 5 min export takes more than 6 min and before between 3 and 4  min.

That's all
