That would be a shame.
It makes a huge difference when shovling bits across my DSL line to my
-stable laptop. Running netperf from a -current alpha with newreno, I
consistantly see 650-700Kb/s. From a -stable i386 without newreno, I
see variable results from 300-500Kb/sec with large stutters, so to
speak, where there is no traffic at all for one second (or at least I
don't see any packets in systat -tcp 1).
I hope this problem can be fixed -- I was actually hoping that newreno
could be MFC'ed.
