@jkaczman I think that failed bencher report is noise here

@jkaczman I think that failed bencher report is noise here

Probably. I'll be replacing Bencher this evening with x86 spot instances from AWS running within the metal bench to supplement the current arm64 Graviton data, which should fix the noise via the extra work our bench does to eliminate variance and provide 95% confidence intervals. I'll also fix that flaky ctx measure.

@murex971 can you rebase off main to get the new x86 bench in here?
