From 0695c67d170eabe7fb3138612db42a233aed8b3d Mon Sep 17 00:00:00 2001 From: Dixing Xu Date: Sat, 25 Jul 2026 19:38:04 +0000 Subject: [PATCH] perf(core): drop a redundant deepcopy of command kwargs StaticCommandRunner._execute_func deep-copied kwargs, popped "chart" from the original, then deep-copied again. The first copy was overwritten before it was read, so successful commands paid two full deep copies of the caller's payload where one was needed. For commands that take a data payload, technical, econometrics and quantitative all accept list[Data]. With a 1,000-row payload the copy step falls from 5.83 ms to 2.88 ms, and with 5,000 rows from 30.5 ms to 14.6 ms. Successful command behavior is unchanged: the removed assignment was overwritten before its value was read.
