Suggest adding a zero or two to see if the effect is more pronounced:
time seq 1000000 # 10 or 20 seconds in theory
Or...
# patience
time seq 10000000 # maybe 2 to 4 minutes?

I tried 'konsole', 'gnome-terminal', 'xterm', 'rxvt', 'eterm', 'mrxvt' but so
far haven't been able to slow down any other terminal. At first I tried 'em
en masse like so:
LOG=`mktemp -t terben.XXXXXX` C=100000 P="seq $C"; for f in 'xterm -e'
'rxvt -e' 'mrxvt -e' 'Eterm -e' 'konsole -e' 'gnome-terminal -x'
'xfce4-terminal -x'; do echo timing \"$f $P\".... ; $f /usr/bin/time -ao $LOG
-f "%E real, %U user, %S sys, %P CPU :: $f" $P ; done ; cat $LOG
timing "xterm -e seq 100000"....
timing "rxvt -e seq 100000"....
timing "mrxvt -e seq 100000"....
timing "Eterm -e seq 100000"....
timing "konsole -e seq 100000"....
kbuildsycoca running...
timing "gnome-terminal -x seq 100000"....
timing "xfce4-terminal -x seq 100000"....
0:06.89 real, 0.16 user, 0.16 sys, 4% CPU :: xterm -e
0:03.38 real, 0.33 user, 0.38 sys, 21% CPU :: rxvt -e
0:02.00 real, 0.35 user, 0.36 sys, 35% CPU :: mrxvt -e
0:11.23 real, 0.18 user, 0.18 sys, 3% CPU :: Eterm -e
0:03.82 real, 0.16 user, 0.18 sys, 9% CPU :: konsole -e
0:04.17 real, 0.32 user, 0.42 sys, 17% CPU :: gnome-terminal -x
0:01.95 real, 0.17 user, 0.20 sys, 19% CPU :: xfce4-terminal -x
But that code can't create the second tab, and doesn't reproduce the
current bug. It shows 'eterm' is slowest, ordinarily. Note that I've
used a '/usr/bin/time' command, as every shell seems to have a
different internal 'time'.
I tried the above with C=1000000 and the tail is surprising:
timing "xfce4-terminal -x seq 1000000"....
0:32.00 real, 1.60 user, 1.74 sys, 10% CPU :: xterm -e
0:27.04 real, 3.95 user, 4.04 sys, 29% CPU :: rxvt -e
0:18.36 real, 3.41 user, 3.86 sys, 39% CPU :: mrxvt -e
1:54.52 real, 2.02 user, 1.97 sys, 3% CPU :: Eterm -e
0:37.18 real, 1.64 user, 1.80 sys, 9% CPU :: konsole -e
0:12.29 real, 1.85 user, 2.62 sys, 36% CPU :: gnome-terminal -x
Not a copy & paste error, the last 'xfce4-terminal' never runs. This works:
rm /tmp/foo ; xfce4-terminal -x /usr/bin/time -o /tmp/foo -f "%E real,
%U user, %S sys, %P CPU " seq 100 ; cat /tmp/foo
0:00.00 real, 0.00 user, 0.00 sys, 0% CPU
...but not these:
rm /tmp/foo ; xfce4-terminal -x /usr/bin/time -o /tmp/foo -f "%E real,
%U user, %S sys, %P CPU " seq 10000 ; cat /tmp/foo
cat: /tmp/foo: No such file or directory
rm /tmp/foo ; xfce4-terminal -x /usr/bin/time -o /tmp/foo -f "%E real,
%U user, %S sys, %P CPU " seq 1000000 ; cat /tmp/foo
cat: /tmp/foo: No such file or directory
The 'time' command might be suspect, except the other X terminals don't seem
to be effected.

I'm not sure, how do I check those?
HTH...
