That's part of the scheduler, which is not tied to the UI updates.

Are you using an ext3 file system (or other file system with very slow delete times) without enabling the "Delete files slowly" setting in mythtv-setup? If so, please let us know and ask for help configuring Myth on the mythtv-users mailing list.

  • Ticket #7604 – Description

    initial v1  
    11When I delete a recording through the frontend it takes over 15 seconds until the record is deleted. There is one very slow query that takes over 13 seconds:
    2 
     2{{{
    33SELECT DISTINCT channel.chanid, channel.sourceid, program.starttime, program.endtime, program.title, program.subtitle, program.description, channel.channum, channel.callsign, channel.name, oldrecduplicate, program.category, sched_temp_record.recpriority, sched_temp_record.dupin, recduplicate, findduplicate, sched_temp_record.type, sched_temp_record.recordid, program.starttime - INTERVAL sched_temp_record.startoffset
    44MINUTE AS recstartts, program.endtime + INTERVAL sched_temp_record.endoffset
    … …  
    3333AND oldrecstatus.title = program.title )
    3434ORDER BY sched_temp_record.recordid DESC
    35 
     35}}}
    3636Here is the explain of this query:
