Yes, it is. I have been trying to fix that issue. What 62 projects are you using? JBoss AS? I would like to test with a similar environment if possible.

Arquillian Cruiser View slows down Eclipse ------------------------------------------ Key: JBIDE-14523 URL: https://issues.jboss.org/browse/JBIDE-14523 Project: Tools (JBoss Tools) Issue Type: Sub-task Components: testing-tools Reporter: Aslak Knutsen Assignee: Snjezana Peco Fix For: 4.1.0.Beta2 Not 100% sure what is going on here, but when I have the Cruiser View open, Eclipse slow's to a holdt for about 10s on save. Freezing the main thread, which makes the hole thing useless. In the Arquillian Cruiser view there are 62 projects shown(+ sub Test classes etc). It takes about 10s to start/open the view as well. Is it checking 'all' projects when a single file is saved? How is the content of the Archive calculated? Could the calculation be processed in a separate thread to avoid freezing the main GUI?
