i think Lee is well aware of that - nevertheless his data point shows that even the relatively low number of latency fixes that went into 2.6.10 (compared to what is pending in -mm and in -RT) are a step in the right direction. I'd guess the biggest win was the ACPI related latency fix, and maybe the softirq fixes.
