Isolyth
SourceLoad-tested Isolyth's MCP tool-calling endpoint with 100 concurrent virtual users via Locust, sustaining ~535 req/sec at p95 latency of 160ms with 0% error rate; benchmarked WASM-sandboxed code execution against plain tool calls, showing only ~15-30ms of added latency overhead from sandboxing —proving security isolation came at min performance cost
