Opinions about code performance

I timed a single loop of my code with time, and got the following statistics. Could anyone please comment as to whether the performance is about normal or actually there are too many allocations which should be reduced to imprve on performance? Thanks

71.433633 seconds (218.69 M allocations: 15.430 GiB, 5.72% gc time)

Probably, although hard to know without seeing the code…
