There are native alternatives like HPCC which claim to perform better.
The goal with performance is almost never to get the maximum possible performance but the best peformance/effort ratio for your needs. This is true even for performance-critical applications. As there are diminishing returns, every increase in performance costs more than the previous. Very, very few applications are willing to invest an extra 30-50% effort to go from 98% (of maximum performance) to 100%.
As to concurrent access -- see my other comment (depends on use-case).
