I believe the performance problems are caused more by buggy TCP/IP stacks that
RFC1323 per se.  If you don't understand IP options, you are just supposed
to ignore them.  Unfortunately, it seems that many systems don't.  Someone
even reported that some Annexes dump core when they see packets with IP
options in them!
