Another big jump, but now it was my job to run benchmarks in the lab, and write white papers that explained the new products to the world, as they were launched. I was mostly coding in C, tuning FORTRAN, and when I needed to do a lot of data analysis of benchmark results used the S-PLUS statistics language, that is the predecessor to R.

A Cassandra database cluster had switched to Ubuntu and noticed write latency increased by over 30%. Was there some other program consuming CPU, like a misbehaving Ubuntu service that wasn't in CentOS? top(1) showed that only the Cassandra database was consuming CPU. These can be invisible to top(8). include <sys/time.h>

Chokepoint : Even sharded Berkeley DB was choking under the stress and there was a database crash with recovery taking hours, it had to be replaced. Automate schema management for some remaining databases. Java/Python mostly and some small services in Go/C. Which database do you use? How is your database architected?
