When displaying service views which conain the "Perf-O-Meter" painter, the rendering of the page, especially with a larger number of rows (>1000), could take a lot of time (multiple seconds) for rendering.

This was caused by an unoptimized perfometer rendering/selection algorithm. A workaround with older versions is to remove the Perf-O-Meter painter from the views.
