Add more parameters to the sweeper combinations for FUSE threads and objects.

Adding more parameters to the sweeper combinations for FUSE threads and application workers

What changed and why?

Expanded the parameter combinations in the benchmark sweeper configuration to include more values for testing:

• application_workers: Added values 4 and 64 to the existing 1, 16 combination
• fuse_threads: Added values 1 and 64 to the existing 16 value

This change supports an ongoing investigation that requires testing across a broader range of worker and thread configurations.

Does this change impact existing behavior?

No breaking changes. This only adds additional parameter combinations for benchmarking - existing functionality remains unchanged.

Does this change need a changelog entry? Does it require a version change?

No changelog entry or version change required. This is an internal benchmarking configuration change that doesn't affect the public API or user-facing functionality.

It'd be good to restrict the combinations of app workers and fuse_threads as we don't care about all combinations of these values. Can we specify them as a pair instead?

I had the same suggestion at some point too, but it makes me wonder how feasible it is to maintain and extend a coupled setup like that.

• Does it become more error-prone or something that requires context to update every time?
• Do we really need an increased number of combinations and consequently a stricter sweeper (in mainline), given we only plot 1 object and 16 objects on day-to-day basis; or should this be something one can play around with during investigations on their machine?
• Will our Jupyter notebooks continue to work with some values/combinations of threads/app_workers missing?
