Summary
🤩
Rockstar🎓
Top SchoolSusan Loverso is a retired senior systems engineer with 13 years post‑WiredTiger/MongoDB experience and a multi‑decade career building high‑performance storage and OS components. She led deep back-end work on the WiredTiger storage engine—contributing low‑level performance optimizations such as switching timers to rdtsc and improving lock/timestamp statistics—reflecting a strong focus on database internals and microsecond‑scale tuning. Her background includes roles at Sleepycat/Oracle, Thinking Machines, and other systems‑centric teams, with hands‑on experience in Mach/OSF, CM-5 file systems, and RAID systems. Based in Southborough, MA, she combines pragmatic consulting experience with an engineer’s obsession for reliable, efficient storage systems. An understated strength is her persistence in fixing subtle calibration and concurrency bugs that materially improve long‑running system stability.

Contributions summary:Susan contributed to the WiredTiger database source tree by implementing and modifying code related to the performance statistics, particularly by switching the timer to `rdtsc` from epoch calls to speed up the timer. They also added new statistics to the locks around the timestamp structures. Further, the user addressed a bug by adding repeated tries to calibrate `rdtsc` and avoid division by zero errors. These modifications demonstrate a focus on performance optimization and database internals.
