When using these patches on statically linked applications, especially C++ applications, you should expect to see a much more dramatic performance hit. For microbenchmarks that are switch, indirect-, or virtual-call heavy we have seen overheads ranging from 10% to 50%.
Ouch! This is independent of other performance hurts, like from the kernel syscall overhead that was the hot topic yesterday. This is pretty crazy.
