Hi all, during the last two weeks I've updated the code to use the bio classification machinery commited by luigi@ in HEAD, and I've added some basic tracking of threads' behavior to drive the heuristics controlling some of the scheduling parameters. The first two milestones are almost complete, even if the proxy destruction code still needs more testing with ongoing I/O. About the third (and last), benchmarking, I've been playing around with microbenchmarks (using fio, http://git.kernel.dk/?p=fio.git;a=summary) and I've started looking at sysbench for its oltp implementation and at TPCC-UVa, an open source tpc-c implementation.
