Yes, too much IPC can definitely slow down the PLT. This has happened a few months back due to diagnostic logging. Looking at the patch, one other possibility (I haven't looked deeply into it) is that the new document.frame() checks sometimes fail and we end up not doing DNS prefetches in cases where we used to?
