Slow response times, but only on few PC's

One of our Notes applications uses a view that is indexed by season and city. In general our users got an excellent response time when they query the database on our company network. A few users however, experience that some queries by season and city are extremely slow (> 3 minutes to wait for a response) but other queries are not. This drives me nuts, because when I execute the same query on the same network and the same database and at the same time, the response time is excellent. The only thing that the users, who got a bad response time, have in common is that they also have a local replica on their PC's. But, if they are in house, they access the server database instead. What could have caused this? I'm at a complete loss.

Additional information. I've checked some things on the user's PC. When I go to the database view, it is nearly impossible to scroll thru the documents in the view. It is extremely slow. Nethertheless his PC doesn't seem to have problems connecting to the server, because a ping to the server on his machine is just as fast as a ping on my PC; nor does he receive timeouts.

Assuming that there is no network problem, what could be the reason why one one PC the views are build up immediately and fast to access and on another machine that is not the case.

Those users who encountered problems have in common that they all received a new laptop recently. Their problems started when they started to use their new laptops.

I now realize that the problem is too complex to analyze. For that reason I've forwarded it to the network- and Lotus Notes specialists of our service provider.
