[R-SIG-Mac] R-gui slow since last update

Tue May 4 09:10:06 CEST 2021

Simon,

I sampled the process of my test (the slowdown). 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.

Yan,

thanks for the reports. I cannot reproduce the slow-down, either (Mac mini M1, Big Sur 11.3).

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<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.

Thanks,
Simon

PS: you may need to install Xcode command line tools if you didn't already:
sudo xcode-select --install

Dear Peter, Simon,

Since I am not that of an expert in programming, is there any way to trace what happens 'under the hood' of the gui to see what exactly slows down the rendering of output on my end?

On the warnings, some more came today. How that happened and the text that came out are below.

Thank you for your help,
Yan

I looked at the Preferences -> Editor (once the window popped up, I clicked on the Editor with a mouse and the error came).
...
2021-05-03 16:50:36.184 R[73442:2450140] Warning: Expected min height of view: (<NSPopoverTouchBarItemButton: 0x7ffd104c17b0>) to be less than or equal to 30 but got a height of 32.000000. This error will be logged once per view in violation.

In another instance, hitting cmd-n (new native editor window) gave me this:

When in native editor, I hit cmd-w (popping the save file request) gave me this:

2019 MB Air here, Big Sur, 4.0.5 off CRAN. I don't see the issue either. (I do see the "...warmup" thing, though.)

Thank you Simon,

Regarding the "NS..." warnings, the following came just now when I closed the plot window (after a ggplot) with a mouse.

2021-05-01 20:53:35.117 R[2344:57535] +[NSSavePanel _warmUp] attempted warmup

Since they are usually random, I will log them for some time, and report back.

Dear all,

Beyond the occasional red warnings about the 'NSPop….' buttons, warmups, etc. and similar issues reported elsewhere here I’ve noted the slowdown of R console with more and more output. 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.
Yan
