This bug report is a bit vague in terms of what the problem is -- the test case hits 3 major subsystems (io, vm, net), all of which have changed rather substantially in the course of 2.6 development. Would it be possible to profile the system using oprofile to get an idea what the hotspots are? Have you compared basic hard disk throughput with hdparm, as well as ensuring DMA is enabled with 32 bit io? What about testing network performance with netperf (or a netcat of /dev/zero)? A few more data points would be quite helpful. Cheers,
