Latency vs Throughput

[Updated: Jan 19, 2011]

I liked this nice little analogy to differentiate between Latency and Throughput - DSO Guy: Latency v Throughput.

A good network latency calculator and the explanation. The Java way to handle it.

Grids, VMs and blind idiots

I just read this blog by the tech team at NY Times. These guys are good. They used Amazon's EC2 and Hadoop to run a massive grid job - ..blogs.nytimes.com/..hadoop. Of course it's all Java. There's more of this kind of stuff in my previous blog: ..got-cache?

And, a nice summary of the state of the art by Cliff Click - the original lead of HotSpot (correct?): ..blogs.azulsystems.com/cliff..

I loved this line from his blog. Haha:

More auto-parallelizing hardware tricks like the Run-Ahead Scout .. .. .. is more like a blind idiot without warmed-up caches & branch-predictors
