I do love running some HammerDB.
Yeah, throwing TB of SQL Server, Windows, and CloudWatch logs at an LLM is great. Having it spin up HammerDB against SQL instances, run multiple tests over many hours, and then compare the results and spit them out is a game-changer. It takes me several weeks to get that set up, run, and evaluated.

I'm using HammerDB for the first time in years... like 10 years maybe? (holy crap) It's all coming back, it's coming back to me now.

Running the TPC-C workload against #PostgreSQL. I really like the flexibility of HammerDB - because I'm doing the same thing with #SQLServer.

The PostgreSQL community would love you for that 🫠. Currently, I’m using the Windows UI of HammerDB for benchmarking.

My first result using tproc-c from HammerDB to compare Postgres versions 12 through 18 on a small server:
* no regressions
* many improvements for Postgres 17.7 and 18.1
* Postgres remains boring for people who search for regressions

Generate synthetic workload on Oracle-DB
In preparation of my session at the #DOAG conference I needed an example DB with significant workload.
Running the TPC-C benchmark with HammerDB was the quick solution.
Here are the steps to do this quite dirty but running:

clues pointed to hammerdb: a pattern such that every "workload" query was followed by one “just checking" query. Round-robin connection distribution among the two numa nodes then ended up with all heavy "workload" queries on one NUMA node and all light “just checking” queries on the other.

Hot Updates are not a nightmare if you tune that fillfactor right! Evading vacuum is like avoiding a bad breakup. Check out the HammerDB TPROC-C benchmark by Avi Vallarapu for proof that bloat can be beaten!

Catbench Vector Search Demo Has Postgres SQL Throughput, Latency Monitoring Now | Discussion
Catbench Vector Search App has Postgres Query Throughput and Latency Monitoring Now - Tanel Poder Consulting
CatBench is a Postgres + PgVector demo application that uses 25k pet photos from a Kaggle dataset for demonstrating how the similarity search features work together with the rest of your application code & schema in the backend (HammerDB Order Entry). The latest version of CatBench has Postgres instance-wide throughput and average query execution latency charts built in now.
Previously you were able to navigate around the recommendation engine for Cat Purchases UI, click on cat photos and find product recommendations, based on what other similar cats had purchased. - Linux, Oracle, SQL performance tuning and troubleshooting - consulting & training.
