From c27e04c88557716bbe8e42b9174ba9b07f90facf Mon Sep 17 00:00:00 2001 From: Christophe Besson Date: Thu, 8 Oct 2026 01:27:58 +0200 Subject: perf(node): sample 9 MB with the size above 9 MB, keep known ids hash_version 3: size + first 4 MB + last 4 MB + 1 MB at the middle, 5.5x faster cold on a USB disk than the 45 MB sample. The cache now serves a hit under whatever version it holds, so no existing id moves.
