Trig functions very slow

Might this help?

using Base.Threads
function ft(n=100_000_000)
    rt = zeros(nthreads())
        @threads for i in 0:n-1
            @inbounds rt[threadid()] += sin(i)
    end
    sum(rt)
end

No idea the state of multi-threading on Numba… although I presume it is off by default & thus doesn’t explain the difference.
