Simon, Yes, I tried to play with touch bar preferences, to no avail.
On the bright side, I also tested your build. Both debug and release version work. There was one NS warning in the release version, but it did not affected at all the test (I was running the same sequence as I described in the original message). In the following transfer are the sampler files for both versions: https://www.dropbox.com/t/xDqbbZma9i0XdHBk I am tempted to slide the new release version to /Applicaitons and use it instead of the one shipped with the CRAN release; is it safe to do so?

However, did you check the Touch Bar settings as discussed previously to see if disabling the app Touch Bar fixes the problem? If it does, there may be hope - I have created a test version at https://github.com/R-macos/Mac-GUI/actions/runs/820226842 at the bottom there is "R-GUI-Build" link under Artifacts which gives you a zip file with R-GUI-Build.dmg image which has both release and debug version which disable the Touch Bar for the console (built for R 4.0.x). Please let me know if that works for you.

Please let me know if you also want the sampler files using the the debug version. Also, if you need me to test the fixes / updates, please don’t hesitate. Yan On May 6, 2021, at 4:30 AM, Simon Urbanek <simon.urba...@r-project.org> wrote: Yan, thank you for the sampler files! From cursory glance the issue seems to be the touch bar, an amazing amount of time is spent in the Apple's touchbar API (almost all of it is in some way related to [NSTextView(NSTextView_TouchBar_API) updateTextTouchBarItems]). That also explains why I was not able to reproduce it, because I don't have a Mac with touch bar and Big Sur. I don't know what is available in the settings, but you may want to see if you can adjust your touch bar system preferences (if I recall there are different options for the touch bar) - the R GUI doesn't use the touch bar at all, so the issue is entirely at the system level. I will look is there is anything we can do to block the touch bar API on our end or otherwise deal with it by have R explicitly handle the touch bar.

I was able to do it without downloading the "Debug" version. There are two files attached. 1. The first one (run at 8:58:14 am) is the replication of my test (the slowdown) using the external editor 2. The second (run at 9:05:09 am) is the replication of my test using the in-built editor While doing the second sampling R also popped the red warnings (if that is useful). I am also answering Peter’s question: my version of Big Sur is 11.3. Let me know what else I can do to help.

However, you can help by sampling the R process and sending the sample to me. You can do that as follows: 1) open R.app 2) open Terminal (under Applications -> Utilities) 3) in Terminal type: sample R 30 4) switch to R and perform your test. You have 30 seconds (that's the number above which specifies how long the sampler will run) to do it. In Terminal it will show the sampler output -in the beginning it will also tell you the location of the text file - it's typically /tmp/R_*.sample.txt - send that file to me. It may not allow you to debug the released version of the GUI, so you may need to download the "Debug" version of the GUI (scroll down) from https://mac.R-project.org You should pick the Mac OS X GUI rev.XXX for R 4.0.x high-sierra-Release.dmg download if you have R 4.0.x. You don't need to install the GUI, you can run it directly from the image so it won't affect your installed version.

Here is what I do to reliably reproduced it on my machine - MacBook Pro 2017 with Touch Bar (sessionInfo() is below). There are no known issues in R 4.0.5 so if you see any please report them. 1. Start fresh R-gui 2. Paste the following text in the editor. Note that lines are commented, this is enough to show the problem. It obvisouly gets worse if R has to evaluate. # m[[ 1]] <- .f(update(fml, . ~ . -x1 + x2)) # m[[ 2]] <- .f(update(fml, . ~ . -x1 + x2 + x3)) # m[[ 3]] <- .f(update(fml, . ~ . -x1 + x2 + x4)) # m[[ 4]] <- .f(update(fml, . ~ . -x1 + x2 + x5)) # m[[ 5]] <- .f(update(fml, . ~ . -x1 + x2 + x6)) # m[[ 6]] <- .f(update(fml, . ~ . -x1 + x2 + x7)) # m[[ 7]] <- .f(update(fml, . ~ . -x1 + x2 + x8)) # m[[ 8]] <- .f(update(fml, . ~ . -x1 + x2 + x9)) # m[[ 9]] <- .f(update(fml, . ~ . -x1 + x2 + x10)) # m[[10]] <- .f(update(fml, . ~ . -x1 + x2 + x11)) 3. Execute as block once - the output appears almost immediately. Execute the second time - the slight delay is already noticeable. Continue to 3-4 time and the delay between the Cmd+Enter and the output is now up to 3-4 seconds and occasional beachball… Thanks, I only have Catalina here and it does not exhibit that behaviour, the execution is always immediate. I'll try on the M1 Big Sur machine on Monday. Thanks, Simon Any help is greatly appreciated.
