test(perf): increase cpu threshold

[Hweinstock]

Problem

#6225

• Didn't think 400% could be exceeded, but this one is especially volatile. Sometimes it barely spikes, and sometimes it goes crazy.

Solution

• Increase to 500%

---

• Treat all work as PUBLIC. Private feature/x branches will not be squash-merged at release time.
• Your code changes must meet the guidelines in CONTRIBUTING.md.

At this point are we even getting value from the performance tests? It feels like we're just going to increase the number indefinitely

I don't think the system stat thresholds are giving us much insight because of their flakiness. The thresholds on fs operations does give us some info, and would catch performance regressions where we somehow accidentally blow up the number of fs operations. However, I think its unlikely an engineer would do this, and performance issues affecting customers would likely be more nuanced than us making a few unneeded fs calls.

Hmmm, looks like these tests are very flaky
