Windows Timer Resolution: The Great Rule Change

Randon ASCII

The behavior of the Windows scheduler changed significantly in Windows 10 2004, in a way that will break a few applications, and there appears to have been no announcement, and the documentation has not been updated. The answer is hardware interrupts. However the scheduler behavior changes dramatically in Windows 10 2004.

The Return of the Frame Pointers

Brendan Gregg

As my former Sun Microsystems colleague Eric Schrock (nickname Schrock) wrote in November 2004 : "On i386, you at least had the advantage of increasing the number of usable registers by 20%. Conclusion I could say that times have changed and now the original 2004 reasons for omitting frame pointers are no longer valid in 2024.

With fixed hardware it’s easy to construct a linked list that will stay in L1, or will always require a trip to L2, or will always require a trip to main memory. One benchmark I wrote measured the L2 cache latency. Standard stuff.

File systems unfit as distributed storage backends: lessons from ten years of Ceph evolution

The Morning Paper

Breaking that assumption allowed Ceph to introduce a new storage backend called BlueStore with much better performance and predictability, and the ability to support the changing storage hardware landscape. But let’s take a quick look at the changing hardware landscape before we go on… The changing hardware landscape.

Welcome to the Jungle

Sutter's Mill

Now welcome to the hardware jungle. For the first time in the history of computing, mainstream hardware is no longer a single-processor von Neumann machine, and never will be again. The free lunch is over. In 2005, however, mainstream computing hit a wall. There’s no going back. That was the first act. I hope you enjoy it.
