go version build with "go build test.go"
vibe.d version built with "dub build --build=release test.d"
Results on my machine:
go: 168.736462ms (overhead ~ 68ms)
vibe.d: 1944ms (overhead ~ 1844ms)
Why creating of vibe.d tasks is so slow (more then 10 times)???
fwiw I have 151ms total time for go; 740 ms for ldc (O2 and
singleobj), and 760ms for dmd. on an old zoostorm running 64bit
arch linux.
microbenchmarks may be testing many strange things, and it
requires more expertise than I currently have to know where this
might come from.
