When I installed openSUSE 12.1, performance on my computer took a severe dive. A kernel update improved things somewhat, but things got to the point where I was seriously considering buying a new computer to get decent performance again. I installed 12.2 a couple of days ago and find performance is much better than 12.1. However, there's still the problem with Seamonkey 2.12 where it locks up solid for 15-20 seconds.
What have you done to diagnose the issue? Is the issue I/O related? [is you HD like on excessively] Do you consistently have high swap levels? If you run top do you see the box in wait-state frequently? Have you verified your DMA, etc... settings with hdparm? Do you see errors in dmesg? What are you doing when Seamonkey locks up? Is it during network operations... do any other network applications 'hang-up'? When Seamonkey locks up is the desktop otherwise still responsive? Because there is no general issue with 12.1 / 12.2; this almost certainly relates specifically to your hardware or configuration.
