Hello Varnish community,
I've just posted an article  about comparing the performance of Varnish
Cache on two similar
machines - the main difference is the CPU architecture - x86_64 vs aarch64.
It uses a specific use case - the backend service just returns a static
content. The idea is
to compare Varnish on the different architectures but also to compare
Varnish against the backend HTTP server.
What is interesting is that Varnish gives the same throughput as the
backend server on x86_64 but on aarch64 it is around 30% slower than the
Any feedback and ideas how to tweak it (VCL or even patches) are very
