NV Web function performance

["Fang LI" <lifang@cn.ibm.com>]

My NV Web function seems very slow and unstable,
I'm using NV6.0.2, Web browser is IE5.0+jre 1.3
It's very slow to open the map, and when I double click some submap,
sometimes it got no response
then I have to restart IE to reopen the web client.
I also tried the Java application that NV provided under the
htdocs/download directory, seems with the same problem.

And the background picture can not seen in web client, is there any way to
add it?

Anybody can give me some advise that if I can tune something to improve the
performance?

Best Regards
