So why didn't you ask about that instead? Something like: "I just moved my system up to sid and now it is behaving very sluggishly, any insights?" would have been appropriate. Anyway, The first thing you should start doing is leave a 'top' instance running to see if you can catch anything interfering with the system. Also, review all the running services and see if there is anything new running since the upgrade that may be causing a problem. Keep an eye on your memory usage as well. In sid you're more likely to encounter bugs and a memory leak bug in some app would ultimately lead to a sluggish system as it tries to swap all the time. Tracking this down can be difficult, so you have to keep at it -- pay attention to what is happening when the response slows down. hth A
