Text symbolizer is a good order of magnitude slower than any other symbolizers for a variety of reasons: drawing text is slower, if you have any halo, they are real peformance killers, and moreover, we do run a label conflict resolution algorithm that does quite a bit of geometric checks, slowing it down further. The only cure I know for this is to carefully enable labels only beyond a certain zoom level, so that labels in the display area are few, and if you can, to disable antialiasing.
