Just guessing :-) You'd want one, sure. But (unless I'm missing something) it doesn't seem that increasing the number of outstanding messages would *require* it (your performance would just suck otherwise). If you treat the number of outstanding requests as a tunable (per mount, per network type) you'd be able to use the same protocol over minimal links as on tcp. dave said: > Wasn't IL somewhat abandoned because to make it as good > as TCP you basically had to implement TCP anyway? My impression is that it was pulled from mainline mostly because it was seen as being too much work to maintain for a small group. It's also not really sensible to talk about "as good as" without defining your context. Over fast, local networks, IL is faster than TCP. It's not as generic, but that's not the same as "worse". erik said: > why is using nat to make many hosts look like one a bad thing? I suspect the reaction is based on being forced to use it when you'd rather not, like many residential ISPs require. It's particularly upsetting when the CPE doesn't even have a globally routable address. aside: i made the il connection. i think you've got either good luck or a good config on your end. it didn't want to ask dns for some reason. --Apple-Mail-2-82175770 content-type: application/pgp-signature; x-mac-type=70674453; name=PGP.sig content-description: This is a digitally signed message part content-disposition: inline; filename=PGP.sig content-transfer-encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.8 (Darwin) iEYEARECAAYFAkvaQMsACgkQyrb52b5lrs4anwCdE8nhAxoppnQFUexVgpF1kmi/ vmAAoIXPWXLLK30BCPm7V/eJBbtxteyS =oakb -----END PGP SIGNATURE----- --Apple-Mail-2-82175770--
