perf: cut allocations
Summary of Changes
Hello!
I found a few "low hanging" allocations that can be deferred until needed or even skipped entirely.
With all the optimizations combined, we can see the best improvement for
simple, static routes (like a /status endpoint) that do not read the Route
from the request context via CurrentRoute and do not populate any vars.
On these routes, we can process requests with a single allocation for the
RouteMatch object. Previously there were 9 extra allocations.
For said routes the processing overhead (ns/op) in mux dropped by 75%, which is
a speedup of 4x.
Other routes can expect to see a double-digit percentage reduction in both processing overhead (ns/op) and allocations as well. These are driven by merging the context population into a single operation, eliminating two of ten allocations.
(Eliminating that last allocation for the RouteMatch in the best case
requires significant refactoring to maintain full backwards compatibility.
Something for another day.)
Each commit message contains benchmark results for showcasing particular (micro) optimizations in reduced allocations and in a few cases notable direct CPU time savings.
I also ran longer benchmarks with 100 repetitions in multiple settings on different generations of (server) CPUs. First, there is the full set of benchmarks in this repository and second, the popular benchmarks https://github.com/julienschmidt/go-http-routing-benchmark.
All but the last change are entirely "free", as in they do not cut features for
gains in performance. The last change for omitting the Route from the
context is behind an optional flag that users can opt in when they do not read
the Route from the request context.
Said flag is stored local in a Router, so users can enable/disable the flag
on Subrouters individually.
Benchmark results
I added all the new benchmarks onto a baseline branch for comparing the
performance of the changes, tip is 0eba4f5731f329d9a95b67359e795344343a6119.
I'm running these tests on "shared" compute instances (and my Laptop), so expect some noise (and frequency scaling on the i7).
mux project benchmarks
You can reproduce these benchmarks using docker, pinned to CPU 1:
docker run --rm --pull always -v /logs:/logs --cpuset-cpus 1 -d golang:1.18 bash -exc 'git clone https://github.com/das7pad/mux.git && cd mux && for branch in baseline perf-cut-allocations; do git checkout "$branch" && go test -benchmem -bench . -count 100 -timeout 1h > "/logs/$branch-all.txt"; done; go install golang.org/x/perf/cmd/benchstat@latest; benchstat /logs/baseline-all.txt /logs/perf-cut-allocations-all.txt > /logs/compare-all.txt'

If you read this far, please consider running benchmarks for your own use cases
of mux and report back any changes. Thanks!
go.mod override
You can use the following override in your go.mod file:
replace github.com/gorilla/mux v1.8.1 => github.com/das7pad/mux v1.8.1-0.20220803193445-4e593050ec93
Optionally, you can enable the flag for not storing the Route in the request context:
m := mux.NewRouter()
m.OmitRouteFromContext(true)
Thanks for the PR @das7pad. hopefully, in the coming weekend, I should take a look at the PR.

FWIW: The commits of this PR were cherry-picked into MinIO's fork of mux. The fork powered the MinIO server for the past 7 months, via https://github.com/minio/minio/pull/16456. This exposure gave the PR a very decent "manual test in production". (For context: MinIO is a popular self-hosted S3 compatible object storage server.)
@coreydaley , any chances you could have a look and maybe get this merged? Thanks.
@AlexVulaj AFAIK this looks fine, would you mind also taking a look at it?
Left a few comments - it also looks like something (unrelated to this PR) is triggering a flag with the security scan for go 1.21. @coreydaley we can likely ignore that for this PR but we should take a deeper look into that.
