Reduces process-wide heap (inuse_space) by 60kB by using a pointer to
a fixed-sized array instead of a slice of a fixed size.
Before:
119.44kB 23.43% 23.43% 147.88kB 29.01% golang.org/x/net/http2/hpack.addDecoderNode
After:
59.72kB 13.28% 39.85% 87.94kB 19.56% golang.org/x/net/http2/hpack.addDecoderNode
(This is all work from an init func in http2/hpack)
Doesn't seem to affect runtime performance.
Measured with:
$ cat huffman_test.go
package main
import (
"testing"
_ "golang.org/x/net/http2"
)
func TestMem(t *testing.T) {}
$ GODEBUG=memprofilerate=1 go test -memprofilerate=1 -memprofile=mem.prof -v .
=== RUN TestMem
--- PASS: TestMem (0.00s)
PASS
ok huffmem 0.052s
$ go tool pprof --inuse_space mem.prof
