A system that feels fast to the user is important and I really appreciate this. I just like to make one request: Please develop some kind of benchmarks and reproduceable tests so that we all can measure the difference. Real numbers speak for themselves...
That could be a tricky thing. The question is: How does one measure that a system "feels fast/responsive"? I think that this is mostly based on personal impressions of a user and it's not that easy to express this by numbers.
Some things that come directly to my mind: * bootspeed * How long does it take on a freshly started system to start OOo? * under a defined workload (some disk I/O work), how long does a certain (to be defined) action take. Those are hardware dependend but on the same hardware with a fresh installation (a defined test system), the performance enhancements should show a difference.
However there has been some work for measuring responsiveness of the Kernel by Con Kolivas. His tool is called interbench (interbench.kolivas.org). Maybe this is a good point to start.
It might be a start if it is close enough to real workloads, Andreas -- Andreas Jaeger, aj@suse.de, http://www.suse.de/~aj SUSE LINUX Products GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GPG fingerprint = 93A3 365E CE47 B889 DF7F FED1 389A 563C C272 A126
