Performance difference on Windows — Node+Hono+EJS faster than Bun+Hono+EJS

[chandra3145]

Hi Team,

We were doing some benchmarking with Bun+Hono+EJS vs Node.js+Hono+EJS and noticed an interesting platform-specific difference. According to the bun-http-framework-benchmark
, Hono on Bun should achieve ~64k throughput vs ~27k on Node.js.

To verify this, we created a simple benchmark repo here:
👉 https://github.com/chandra3145/bun-node-benchmark

We ran ApacheBench (ab) with the following command on both Mac and Windows:

For bun - ab -n 1000 -c 1 http://localhost:8080/complex

for Node - ab -n 1000 -c 1 http://localhost:8081/complex

Mac OS (M1)

Bun is 16.9% faster in requests per second on the complex route.
(Aligned with expectations)

Windows

Node.js is actually 8.5% faster than Bun on the same complex route.
(This is opposite to the benchmark results reported earlier)

Question:
Has anyone else observed this performance difference specifically on Windows?
Could this be related to:

Yes of course
Windows is not a priority for Bub at performance (and it's great who cares about windows servers it is useless)
