Bug ID: 255551
Summary: FreeBSD sort much slower than GNU or NetBSD
Product: Base System
Version: 12.2-STABLE
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
This isn't really a problem, since FreeBSD's sort command is more than fast
enough for my purposes, but it seems worth reporting in case it exposes an
undiscovered problem that might be easy to fix.
All tests were run on the same machine, a ThinkCenter i5 with 8G RAM. NetBSD
running under VirtualBox.
NetBSD netbsd9.acadix bacon ~/Prog/Src/peak-classifier 435: (pkgsrc): time
sort -n -k 1 -k 2 -k 3 pc-gff-stripped.bed > /dev/null
1.409u 2.548s 0:03.95 99.7% 0+0k 0+0io 0pf+0w
FreeBSD coral.acadix bacon ~/Prog/Src/peak-classifier 1005: time sort -n -k 1
-k 2 -k 3 pc-gff-stripped.bed > /dev/null
24.574u 0.795s 0:25.37 99.9% 55+172k 0+0io 0pf+0w
FreeBSD coral.acadix bacon ~/Prog/Src/peak-classifier 1006: time gsort
--parallel=1 -n -k 1 -k 2 -k 3 pc-gff-stripped.bed > /dev/null
3.005u 0.149s 0:03.16 99.3% 152+177k 6+0io 3pf+0w
I generated a simpler file using just column 2 from the bed file and ran a
simple sort -n on it (no -k flags). Results were similar, so the performance
difference is not limited to multicolumn sorting.
Results are the same on 12.2 and 13.0.
