[PR #9835/32ccfc9a backport][3.11] Adjust client payload benchmarks to better represent real world cases

[patchback]

This is a backport of PR #9835 as merged into master (32ccfc9).

We are interested in benchmarking various payload sizes at different buffering cut offs to see the memcpy and buffering impacts

2048 was too high as most small payloads are < 1024
32768 was two high as it always did two reads for this case so it wasn't giving us a case for a single large read.
1MiB was fine but 512KiB is also fine as it still gives us a benchmark for a multi-read case but there was no need to go that high as it didn't change the profile and only made the benchmark run longer

Note I'm testing on mac. I'm going to test on linux shortly since thats where the bulk of our users are. The breakpoints are going to be dictated by the kernel. If the linux buffer sizes are lower by default, I'll adjust the 2nd one down some more. Ideally we keep it as high as possible to see the memcpy effects but not so high that the message ends up in multiple reads

The 30000 size is good for linux as well as it results in a single read.
