There was an -mm3 patch for 2.5.42. There's an -mm2 patch for 2.5.43 there now, too :) > > There's quite(!) a descrepency between Joern's and my X11 performance.

A test with 2.4.19-jl6 confirms this (with reiserfs, rather than xfs): http://pkl.net/~node/lad/latency-tests/2.4.19-jl6-ll/3x256.html Also, by the by, a 2.5.43-mm2 test is now showing similar disk read results to the -jl6 kernel: http://pkl.net/~node/lad/latency-tests/2.5.43-mm2/3x256.html Bob
