i think the real takeaway is that postgres devs aren’t fucking around when it comes to performance

@jacqueline indeed that was a deep dive for a very little motivation! I'm impressed at the dedication.

@jacqueline in a meeting in a few years:

"So, why did we decide to go with PostgreSQL back then?"

"Well, it's complicated!"

@jacqueline I’m going to be thinking about this every time somebody asks “Is CI running a little slow today?”

@pmidden @jacqueline they discovered that xz had a backdoor because it took 0.4 seconds longer to log into ssh

@pmidden @jacqueline the recent XZ backdoor was initially uncovered by a postgresql dev who noticed some benchmarks were running **sightly** slower than normal.

@jacqueline There’s this book called “a cuckoo’s egg” by a guy named Clifford Stoll that you might like 🙃

@sandorspruit @jacqueline 75 cents difference - I’m reading this right now. For the umpteenth time.

OMG if you ever did an strace and like each ms the LD_LIBRARY_PATH is walked only to find what it needs at the very end of it.

This is how the xz vulnerability was discovered: a Postgres dev was doing some performance testing, and noticed that ssh was working harder than normal.
