I don't know what's fast or slow is for you. But I can say in general I have no performance-problems with TST. I tested the new version of Sidebery, the last days, and performance-wise it seems around the same. Some difference is the animation-speed, which out of the box on TST is a bit slower than with Sidebery. But that's a configuration-detail.
