Root cause: each email pays an ffi.copy(p+i, lua_str, n) boundary (~50 ns/call). At 26 emails = ~1.3 us pure boundary; at 2800 emails (100KB) = ~140 us pure boundary. Meanwhile Person_encode appends Lua-string refs to an out table (no FFI boundary) and pays ONE bulk table.concat memcpy at the end regardless of count. Per-field boundary work beats per-message bulk work only when field count is very small.\n\nFor 4ql's stated use case (net.box send path), typical Tarantool RPC payloads are \u003e=1 KB — exactly the regression zone (1.4-2.7x slower). Win window (\u003c100B) is too narrow to justify a separate API surface, especially since pb.encode is already 462-470ns at that size — saving 200ns on a sub-microsecond operation is not a meaningful net.box gain.\n\nThree abandoned attempts now (per-byte b:alloc cliff, v2 two-pass bulk reserve, this single-pass backpatch). All hit the same per-field FFI boundary tax. Closing as 'not viable on current LuaJIT'. REVIVAL CRITERIA: a future LuaJIT that can sink FFI calls into traces (so per-field ffi.copy stops paying the boundary cost), OR a use case where caller passes pre-cdata-cast strings (no per-email lua-string -\u003e cdata copy), OR a hand-written C encoder behind the c_runtime FFI surface (different path entirely — see c0i).","labels":["api","encoder","perf"],"dependency_count":0,"dependent_count":0,"comment_count":0} {"_type":"issue","id":"tarantool-protobuf-86g","title":"Encoder: two-pass with exact size precomputation","description":"Walk fields once to sum byte sizes, allocate the final string at exact size, walk again to write.

The 100 KB jump (+34%) is +where this matters: every encoded byte saved on the per-prefix call +amortizes across 26+ emails and the larger string fields. + +Decode is genuinely flat — the decoder doesn't emit length prefixes; +this is encoder-only. + +**Notes / caveats:** + +- The change is parity-safe by construction: `CHARS[i]` returns the + same interned 1-byte string that `string.char(i)` does. The 752-test + suite confirms this empirically across both `full` and `runtime` modes + (runtime-mode wrappers also re-emit the inline fast path). +- This subsumes part of what lkz / 86g (ffi.new buffer rewrite) were + meant to address. A separate hand-spike of the full FFI buffer rewrite + *regressed* across all sizes (0.31×-0.77×) — the `out` table + + `table.concat` shape is already well-tuned in LuaJIT; the remaining + per-line cost was the `string.char` C-call, and that's what 2ri kills. + See drm notes for the spike data. +- Memory: `wire.CHARS` is 256 interned 1-byte strings + the table + itself. Built once per process, ~12 KB total — negligible. + +**Commit:** see the 2ri commit immediately following this entry. + +--- + ## 2026-05-24 — qwt + 2sn: inline proto2 extension writers/readers and table.new(N, 0) for packed lists **Tasks:** diff --git a/cmd/protoc-gen-tarantool/internal/gen/gen.go b/cmd/protoc-gen-tarantool/internal/gen/gen.go index 777d62b29899b63b8225baafd1cd89f6a5959acf..8194a195ad3fa978fb78cf826a692b3cd3f29e24 100644 --- a/cmd/protoc-gen-tarantool/internal/gen/gen.go +++ b/cmd/protoc-gen-tarantool/internal/gen/gen.go @@ -214,6 +214,9 @@ w.line("local string_byte = string.byte") w.line("local utf8_len = require('utf8').len") w.line("local band = bit.band") w.line("local rshift = bit.rshift") + // 256-byte lookup table replacing string.char(b) at length-prefix + // emit sites. ~27% faster on small Person encode (see wire.CHARS). + w.line("local CHARS = wire.CHARS") // table.new(N, 0) presizes a list's array part to avoid the rehash // cascade that fresh-`{}` tables pay as items are pushed.
