Did you make some comparisons with Giac ? Some benchmarks from Roman Pearce and my own tests, about 2 years old.
Roman used an Intel Core i5 4570 3.2 GHz with 8 GB DDR3-1600 running 64-bit Linux (4 cores, 4 threads, 6M cache, turbo 3.2 -> 3.6GHz). I also checked Giac on my Mac (Core i5 2.9Ghz, 2 cores, 4 threads) Groebner bases mod p are computed for the fastest machine prime supported by each software. For mgb and Singular p=2^31-1, for Magma p=11863279, for FGb p=65521, and for Giac p=16777213.
