Research direction

Start with the JAX benchmark test and its two parametrizations, then compare their runtime with the recent PR and the JAX version in use. Reproduce the multi-hour execution and determine whether the regression comes from PyTensor or JAX; done means identifying the cause and confirming a reasonable runtime.
