I've never heard anybody suggest that nginx with luijit suffers from performance issues.
- steveklabnik 3y agoI worked at Cloudflare, but long ago, and not on this sort of thing. Cloudflare has extensive experience with both of these things, including employing Mike Pall for a time. That they've invested in Pingora instead is an interesting data point precisely due to that deep expertise at scale. As they say in the link that started this subthread: > In production, Pingora consumes about 70% less CPU and 67% less memory compared to our old service with the same traffic load. The savings come from a few factors. > > Our Rust code runs more efficiently compared to our old Lua code. On top of that, there are also efficiency differences from their architectures. For example, in NGINX/OpenResty, when the Lua code wants to access an HTTP header, it has to read it from the NGINX C struct, allocate a Lua string and then copy it to the Lua string. Afterwards, Lua has to garbage-collect its new string as well. In Pingora, it would just be a direct string access.
