BACKGROUND
      R2.9.2 built on  power5 aix5.3 using gcc 4.2.4   (also installed: tcl and tk 8.5.7)
     Access from a Windows XP machine using Exceed v9.0, aixterm (DISPLAY etc. setup)

    export LDFLAGS="-L/usr/lib64 -L/opt/freeware/lib64 -L/opt/freeware/64/lib -L/usr/X11R6/lib -L/opt/freeware/lib"
    export CPPFLAGS="-I/opt/freeware/include -I/usr/lpp/X11/include/X11"

QUESTION
1.  Are there any known issues with tcl/tk? Should I be doing anything different in the configuration?
2. When I try a simple plot command in either configuration   (eg.  plot(sin, -pi, pi)),  the plot window shows up immediately on my machine but the plot itself takes all of two minutes to draw.  I am not sure if the two issues are related.

I would appreciate any help with this.  Thanks.

As you might know, selecting a CRAN mirror normally uses tcltk.  Most  
likely something is wrong with tcltk (not the R package, but the  
library) on your machine.
This is unrelated to the bug above.  In newer versions of R, the X11  
device uses type = "cairo" per default.  This gives prettier results,  
but is slower on (some) network connections.

Use X11(type = "Xlib") before you issue your plot command.  This  
usually results in substantial speedup.  This is an old issue, that  
has been discussed at depth when type = "cairo" was set to be default.
