  "message": "tp: parse appended trace data without copying it\n\nTrace bytes arrive zero-copy into the tokenizer, and then Rpc::Parse\ncopies them straight back out because TraceProcessor needs to own what\nit is given. For APPEND_TRACE_DATA that is a 32 MB memcpy per chunk,\nwhich undoes the whole chain, on the wasm and httpd paths as much as\nanywhere else.\n\nHand the parser the tokenizer\u0027s message instead: TraceBlob holds it for\nas long as the bytes are needed, and the ring buffer moves onto another\nbuffer rather than recycling one still being read. Dispatching a message\nnow means handing over its bytes, so OnRpcMessage() takes an owned\nmessage rather than a pointer and a length.\n\nout/linux_clang_release/perfetto_integrationtests \\\n    --gtest_filter\u003d\u0027*Remote*:*Stdiod*:*ServerUnix*\u0027\n",
