I think a good benchmark would be a 31-bit job with a matrix size in the 6M to 9M range. I don't have a dataset for one of those handy, but one will turn up soon enough from the queue.

The ETA is very stable by the time, say, 5% of the job is complete, so the data handling is more a problem than the time to benchmark; in fact, now that I say that perhaps a tough 30-bit job is better for this sort of benchmark to reduce data size.

A benchmark would include filtering time start-to-finish, and ETA after 5% of the job is done.

When you see a good candidate let us know.

Well, this one took quite a while. Spilled a glass of wine on my laptop keyboard on New Year's Eve and the hard drive started failing the next day.
Bought a new laptop which, after finally being delivered, has finished this factorization.

Approximately 49.2 hours on Core i7-10510U with 12 GB memory for a 5.02M matrix at TD=120.
