Alan Donovan 63dfc2d3a9 internal/lsp/cache: two minor optimizations ... 1. Avoid unnecessary intermediate map updates. 2. Avoid accumulating defers in a loop when the control is simple. Yield: -10% CPU, -37% allocs. Typical results: $ go test -v ./gopls/internal/regtest/bench -run=TestBenchmarkDidChange -didchange_dir=$HOME/w/kubernetes -didchange_file=pkg/util/hash/hash.go Before: BenchmarkStatistics 100 25932206 ns/op 11684109 B/op 75458 allocs/op After: BenchmarkStatistics 100 23294195 ns/op 11293472 B/op 47299 allocs/op Also, move profiling logic outside the loop so that later runs don't overwrite earlier runs. (This doesn't appear to be a problem in practice, presumably because the last run is the big one.)
