After updating to -current as of this morning, I still observe RTTs of 113 ms when pinging from one PE router to the over PE via two P routers. I have been checking the usual suspects, such as duplex-mismatch, but from tcpdumps it looks as if the P routers take two to three douzen milliseconds before they route returning ICMP Echo Replies. Later, I'll try to compile and post a more precise analysis, possibly with timestamped traces, etc.
