I'm having a bit of a performance issue when working with mylyn.
Eclipse is constantly eating up about 100% of one core on my system. And if I activate "Focus on Active Task" eclipse freezes for about 5 - 10 seconds whenever mylyn updates the context.
I'm currently using Zend Studio 7.2, but I had the same issue when testing the new 8 beta.
Does anyone know of a way to improve the performance? I've tried closing all projects I'm not currently working on, but this did not seem to help much.
