List-Unsubscribe: , List-Archive: Hi, I've put up the full set of RPC changes that I'd like to push into 2.4.20 in http://www.fys.uio.no/~trondmy/src/2.4.19-pre10/linux-2.4.19-RPC_ALL.dif The full set of partial patches can be found in the same directory. Patches contain 1) Full set of 2.5.x kmap() changes for avoiding highmem deadlocks. 2) RTT (round trip timing) estimation for improving the UDP timeout + resend mechanism. Algorithm is the standard one as described in the Van Jacobson paper (see http://www-nrg.ee.lbl.gov/papers/congavoid.pdf) 3) Slow start + congestion avoidance algorithms for UDP. Again see the Van Jacobson paper. 4) A couple of minor cleanups. In particular, it would be nice if people could test out the RTT + congestion avoidance. Although it is probably not a cure for all of our UDP problems, I would expect performance to improve on most platforms. In particular, I'd very much encourage those people who reported a performance slowdown with the previous NFS_ALL patch to test this out.
