From f6cd582505429fa95a4cf697507d8f39959f48d1 Mon Sep 17 00:00:00 2001 From: normal Date: Sat, 30 May 2015 00:20:15 +0000 Subject: variable.c: avoid compatibility table with generic ivars This recovers and improves performance of Marshal.dump/load on Time objects compared to when we implemented generic ivars entirely using st_table. This also recovers some performance on other generic ivar objects, but does not bring bring Marshal.dump/load performance up to previous speeds. benchmark results: minimum results in each 10 measurements.
