RHBA-2005:279 - Bug Fix Advisory
Synopsis
db4 bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated db4 packages that fix a performance issue in memory pool allocation
are now available.
Description
The Berkeley Database (Berkeley DB) is a programmatic toolkit that provides
embedded database support for both traditional and client/server applications.
This update fixes a performance regression from 4.0 due to many calls to
_os_sleep() in memory pool allocation. The regression was fixed upstream
4.2 and was released as patch.4.1.25.2 from sleepycat.
All users of db4 should upgrade to these updated packages, which
resolve these issues.
