Better startup times: skip macros #50

Closed l3nz closed 5 years ago

l3nz commented 5 years ago

It would be worthwhile too add some tips section for better startup times, e.g.

time clj -J-Dclojure.spec.skip-macros=true -m recap sv

real    0m2.587s - user 0m6.997 - sys   0m0.332s

versus default:

time clj -J-Dclojure.spec.skip-macros=false -m recap sv

real    0m3.141s -user  0m8.707s -sys   0m0.391s

Writing it here so I don't forget 😸
