R and package binaries for R versions older than 4.0.0 are only available from the CRAN archive so users of such versions should adjust the CRAN mirror setting ( ) accordingly. Please share your ideas about solving the slowness bug in definitive manner.This directory contains binaries for the base distribution and of R and packages to run on macOS.

I have tried it on many Mac computers of various generations (macbooks, imacs, mac mini, over 20 computers) and it was faster on all of them.

If someone wants to try this with the software which is used in the video, you can get it here. It is totally counter-intuitive, that software runs better if it has less memory and graphics resources (since they are used by the other session). It is really awkward way of working, and it is hard to advocate with normal users. This apparently resets the graphics subsystem and cleans the "slow" system state. You can make it fast again if you logout and login (but still keeping the other session), without shutting down the computer. The only problem is that after some time (can't figure out what is triggering it), it becomes slow again.

But it also shows that it could run at full speed. This demonstrates that some Apple bug prevents the software from working normally, either in XQuartz, or at lower level. It was running like this before El Capitan when it became slow. IT RUNS AT FULL SPEED!!! Same program, same computer, same versions of software. Second part of video shows how the program works, if you start the Mac computer, login as one user, and then start another session (without closing first one), and then start the X11 based program which uses XQuartz. Other operations work normally, but use interface is too slow fully productive use. I show only opening of menus by passing the mouse over menu title, but main slowness is actually in resizing windows. I have created a short video to demonstrate the how slow is XQuartz with the Motif based textile CAD software, and a hack to make it faster. # run demo WITH uncover hack (about 300 msec)ĭYLD_LIBRARY_PATH=/tmp/tcl8.5.18/unix:/tmp/tk8.5.18/unix /tmp/tk8.5.18/unix/wish zz.tcl 1 # run demo WITHOUT uncover hack (takes 7-8 secs)ĭYLD_LIBRARY_PATH=/tmp/tcl8.5.18/unix:/tmp/tk8.5.18/unix /tmp/tk8.5.18/unix/wish zz.tcl 0 # speedup req's Xwin (exist OK, too) to get behind If -e bash -norc &]Īfter 50 # req'd else xterm not drawn in time (> ~10ms) # X11/tk/wish demo huge slowdown 10.10+ drawing speed, hack workaround

# put following demo tcl/tk script into: /tmp/zz.tcl

The uncover hack gets us back to only 5x slower. It takes 7-8 seconds to do the same thing, over 100x

On Mac OS X 10.12.5, running on same hardware, On Mac OS X 10.6.8, it takes 70 msec to draw 400 X11/tkīuttons. OS X 10.10+ caused by uncovering a drawing-in-progress The massive increase in X11 drawing speed (20x) on Mac Here is a completely non-invasive way to demonstrate I don't have access to other Mac systems, so I don't know exactly what combination of OS X version, XQuartz version, or hardware, seem to have this problem. I realize that this is not a direct comparison, but a factor of 20 difference in speed doesn't seem right. The same program run on Linux via a modest PC-based virtual machine with 24-bit color takes about 16 seconds. On my Mac mini, the program takes around 42 sec on 8-bit color, and over five minutes on the default 24-bit color settings, which means the 24-bit case is more than 7x slower. To test things, I made a simple X11 program, attached here, which calls XDrawLine() many times.

I think earlier versions of XQuartz might not have had this problem. I also saw drastic slowdown in my own X11 applications, and recently discovered that it seems to be related to whether XQuartz is in TrueColor (24 bit) or PseudoColor (8 bit) mode. Xquartz 2.7.8 / Mac OS X 10.11.1 / Mac mini (Late 2014, Intel Iris Graphics)Īs long ago as Mac OS X Yosemite, some folks have reported graphics slowdowns, for example: It is also generally slow compared to X11 performance on Linux. X11 drawing seems to be 7x slower when XQuartz "Preferences/Output" is not set to "256 colors". Simple test of XDrawLine to probe drawing speed performance.
