@bes1002t: I think throughput is a different issue than this, although it might well be related.
But most important would be for someone to create a I/O concurrency / latency benchmark. Maybe the Phoronix Test Suite is an adequate tool for that? It can also be used for automatic bisecting..
I clearly remember pre-2.6.18 times where I had a much inferior machine and while gent0o's emerge was compiling stuff in the background with multiple threads, I could browse the web switch between programs and play a HD stream without any hickup or stalling.
