A good start is to look at what version of Tcl you've got:
info patchlevel
Then look at the contents of the tcl_platform global array:
parray tcl_platform
See tcl_platform for a list of the output of this command on various systems.
Now, if you are running Unix, you can obtain even more configuration information:
exec uname -a
And for Solaris users, you can find out your processor speed using the following magic incantation:
exec psrinfo -v
(the executable is located in /usr/sbin on this machine at least... :^)
On Linux, you can work out your basic memory usage profile using:
exec free
Unix systems with the luxury of a SYSV ps (like both IRIX and Solaris) can use it to discover useful info about the Tcl process itself:
exec /bin/ps -p [pid] -o {pid sz rss util pcpu time etime comm}And there is also sysconf which is exposed on IRIX systems but not Solaris AFAICT...
exec sysconf
Actually, solaris has sysinfo, but it's not all that useful ;^)
I am rather partial to:
set name xterm exec /bin/ps -Ao fname,pid,pcpu,pmem,vsz,rss,etime | grep $name
-PSE

CL maintains an exhausting, if not exhaustive, list of ways to calculate memory characteristics under various Unix flavors at [L2 ]. Several of these commands give configuration information beyond memory.
