I was a fan of Skype until I encountered some serious issues. Approx 15 minutes into a video chat, I was experiencing some major performance problems.
As shown in the above screenshot, surely enough, Skype was consuming over 50% of my CPU. Meanwhile, the individual I was conversing with also had similar issues. However, while program crashed shortly afterwards, the person on the other end had no such problems. I haven't used Skype since the incident yesterday. I am still at a loss for how to remedy this. Turning off the video and limiting it to audio seemed to have helped the situation somewhat.
A quick search on this topic resulted in a few good troubleshooting tips: here, here and on their official site. Guess this has always been a limitation of the software since it dates back to 2003. This forum thread got me thinking about trying out JaJah.
