These was failing with swarming timeouts, not enough devices, retrying since we've increased capacity.

Looks like Ben's CL ([wasm] Merge the WasmContext into WasmInstanceObject). This CL is expected to regress performance a bit, so it's probably a WontFix.

The performance seems to have recovered in the graph. It was fixed by https://chromium.googlesource.com/v8/v8/+/ff64dfa09207208d3cae0b0a0745b9397adaf9cc
