[j-sim-users] why so slow

[zcm3518]

Hi,
Everyone.
I read the following script and run it on my computer:
<http://www.j-sim.org/experiment/ex1/j-sim/onebottleneck.tcl>
It finished in 10 second. That is good.
I add some codes just before <puts "Start simulation"> to get some visual
feel, and run it again 
It now needs several hundreds seconds to finish.
Why the following code lines make the execution time of the script become so
long?
Is it possible to diminish the execution time?  3x
==============================================================
puts "Set up TrafficMonitor & Plotter..."
set plot_ [mkdir drcl.comp.tool.Plotter .plot]

for {set i 0} {$i<$nc_} {incr i} {
	set k [expr $i+2+$nc_]
     mkdir drcl.net.tool.TrafficMonitor .tm$k
	connect -c h$k/csl/6 at up -to .tm$k/in@
	connect -c .tm$k/bytecount@ -to $plot_/$i at 0
	connect -c h$k/tcpsink/seqno@ -to $plot_/$i at 2
}
! .tm[expr 2+$nc_]-[expr 1+2*$nc_] configure 10.0 10.0; # window size,
update interval
for {set i 0} {$i<$nc_} {incr i} {
	set j [expr $i+2]
	connect -c h$j/tcp/cwnd@ -to $plot_/$i at 1
	connect -c h$j/tcp/srtt@ -to $plot_/$i at 3
}
