seems to be a CPU/JRE problem
i just tried it on a AthlonXP 2000 with 512 MB
with sun-j2re1.5-1.5.0+update01 and Mozilla (on Debian sarge)

java uses between 9 and 25% CPU time

but i found a different problem:

i deleted some nodes/lines from my failed Griesheim upload
and while i deleted some lines, other already deleted
nodes and lines reapeared in other regions on the map
