the CPython benchmarks have an extensive set of microbenchmarks in the pybench package
Try not to care too much about pybench. There is some value in it, but some of its microbenchmarks are also tied to CPython's interpreter behaviour. For example, the benchmarks for literals can easily be considered dead code by other Python implementations so that they may end up optimising the benchmarked code away completely, or at least partially. That makes a comparison of the results somewhat pointless.
