Bug ID: 298810
Summary: Performance issues with sed in base
Product: Base System
Version: 15.1-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
The following command took several minutes with bsd sed:
cat access_log* |sed 's/^.*"\([^"][^"]*\)"$/\1/'
But only a few seconds in GNU sed:
cat access_log* |gsed 's/^.*"\([^"][^"]*\)"$/\1/'
I'm not sure how to reproduce the performance hit, except to use the same sed
statement on a similar httpd log.
I've noticed performance issues with BSD sed vs. GNU sed every great once in a
while, but not often enough to remember how it happened last time.
