It isn't always possible to find recent quantitative analysis for various software approaches to
base design and implementation decisions on. In light of this, I have decided to keep track of
measurements I have made on this web page in a manner that is somewhat presentable to others.
-
AMD64
During my time at a previous job, I was involved in an effort to quantify and explain certain
performance mismatches between a high performance computing application across different
clusters. These are some of the measurements associated with this effort.
-
BPF
In order to justify some design changes to the FreeBSD BPF buffering model for a packet
capture framework I was working on, I decided to develop a stochastic model of the
FreeBSD BPF implementation. These are the measurements taken to verify accuracy of
that model.

gettimeofday
The cost of the gettimeofday system call across various operating systems and IA32 processors.
