RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Phil Anderson 2015-09-10 04:10:02 UTC 
Description of problem:
Since upgrading to RHEL 7.2 beta, rhythmbox now chews up 35s CPU time on startup and take 10s+ to search for an artist/album/etc.  Previously startup only took a couple of seconds and the search operations were nearly instant.  This is on a catalog of 15,000 songs.

I tried disabling all plugins as well as rebuilding the library from scratch but the issue persisted.

Version-Release number of selected component (if applicable):
rhythmbox-2.99.1-4.el7.x86_64

How reproducible:
100%

Additional info:
I haven't run callgrind, but I did a few pstacks while it's starting up and libdbus features at the top of the stack most of the time.

Comment 2 Phil Anderson 2015-09-15 00:02:00 UTC 
As rhythmbox hasn't really changed since 7.1, this issue might be assigned to the wrong component.  Note that during rhythmbox startup, caribou and dbus-daemon also chew up significant resources:
