Clojurians Log v2

This is interesting, on GHA with babashka dev (master) I get:

Run bash <(curl ) --dev-build

Moving /usr/local/bin/bb to /usr/local/bin/bb.old
Successfully installed bb in /usr/local/bin
The current machine does not support all of the following CPU features that are required by the image: [CX8, CMOV, FXSR, MMX, SSE, SSE2, SSE3, SSSE3, SSE4_1, SSE4_2, POPCNT, LZCNT, AVX, AVX2, BMI1, BMI2, FMA].

interesting observation: the locally PGO compiled binary without the -march=comaptibilty seems to be ~100ms faster than the CI compiled binary. Maybe the special instructions at play here?

CI:
bb -e '(time (loop [val 0 cnt 10000000] (if (pos? cnt) (recur (inc val) (dec cnt)) val)))'
"Elapsed time: 334.463748 msecs"
10000000

local:
bb -e '(time (loop [val 0 cnt 10000000] (if (pos? cnt) (recur (inc val) (dec cnt)) val)))'
"Elapsed time: 259.723079 msecs"
