eclipse very slow to start a plugin install

Question

I use eclipse for my projects.

When I want to install or update a plugin, it is very very slow to calculate dependencies ( about 5 to 10 minutes) and then it is fast to download files and install them.

Do you know how to solve that ?

It is on Ubuntu 10.04 with latest patches + eclipse 3.6.1

No proxy is used. I noticed the problem with several computer at home, but I do not have this problem at work (I use a proxy at work)

Answer 1

Try to uncheck the option "Contract all update sites" before installing your selection. Because p2 would try to check the dependency from all the available update sites(download the metadata repository firstly) when checking that option.
