+- Depending on your simulation, cocotb 1.2 might be roughly 20 percent slower than cocotb 1.1.
+ Much of the work in this release cycle went into fixing correctness bugs in the scheduler, sometimes at the cost of performance.
+ We are continuing to investigate this in issue :issue:`961`.
+ Independent of the cocotb version, we recommend using the latest Python 3 version, which is shown to be significantly faster than previous Python 3 versions, and slightly faster than Python 2.7.

+Please have a look at the `issue tracker <https://github.com/cocotb/cocotb/issues>`_ for more outstanding issues and contribution opportunities.
