For what matters:

ghigo at venice:~$ gnome-terminal -e "time -po /tmp/log python -c 'print 
(\"x\"*40+\"\n\")*1000000;'"; 
ghigo at venice:~$ cat /tmp/log
real 109.87
user 0.08
sys 0.57

ghigo at venice:~$ xterm -e sh -c "time -po /tmp/log python -c 'print 
(\"x\"*40+\"\n\")*1000000;'"; 
ghigo at venice:~$ cat /tmp/log
real 117.11
user 0.10
sys 1.21

ghigo at venice:~$ konsole -e sh -c "time -po /tmp/log python -c 'print 
(\"x\"*40+\"\n\")*1000000;'"; 
kdecore (KProcess): WARNING: _attachPty() 11
ghigo at venice:~$ cat /tmp/log
real 26.55
user 0.08
sys 1.11

ghigo at venice:~$ aterm -e sh -c "time -po /tmp/log python -c 'print 
(\"x\"*40+\"\n\")*1000000;'"; 
ghigo at venice:~$ cat /tmp/log
real 4.06
user 0.09
sys 1.24

ghigo at venice:~$ rxvt -e sh -c "time -po /tmp/log python -c 'print 
(\"x\"*40+\"\n\")*1000000;'"; 
ghigo at venice:~$ cat /tmp/log
real 4.53
user 0.09
sys 1.54


Conclusion: gnome-terminal is 4 time slower than konsole; rxvt is 6 times 
faster than konsole; xterm is slow as gnome-terminal. aterm is fast as 
rxvt...
