描述

The "Garbage Collector" profile track is sorted to the top of the perfetto UI by https://github.com/bazelbuild/bazel/blob/ee72e6ddbcf19db6e4ddf127bde56ca5676de780/src/main/java/com/google/devtools/build/lib/profiler/ThreadMetadata.java#L89. In paticular, it's often useful to examine the GC track in conjunction with the memory tracks. While it's possible to reorganize the tracks in the Perfetto UI, I propose to move the GC track down by the rest of the system stats by default.

研究方向
The issue proposes moving the 'Garbage Collector' profile track in the Perfetto UI to be near system stats. The relevant code is in ThreadMetadata.java at line 89, where the track sort order is set. Examine that file to understand the current sorting mechanism and determine how to change the order of the GC track. Check the issue comments for any additional context or suggested approach.
