Hi
I've been investigating a performance "problem" with uuid generation
https://jasonaowen.net/blog/2017/Apr/13/benchmarking-uuids-v2/, which I
couldn't reproduce on my computer while it occurred on my servers. After
a few tests, it seems to come from uuid-ossp being replaced with
libuuid… when linking postgresql with uuid-ossp I get the exact same
performance between uuid_generate_v4 and gen_random_uuid. When linking
with libuuid, I get the same results as those displayed in the linked
webpage (I can provide numbers).
Is this an expected difference ?
Please tell me what I can provide if required.
Regards
Marc
