Slow playlist opening


Rob_G

Recommended Posts

 Playlists performance seems to be going downhill on my system.  Opening playlists like 'All Games' for Arcade takes over 30 seconds now.  Also entering my Arcade Platform Category makes 2 beeps instead of 1.   Some playlists seem affected worse than others.  Even small playlists can sometimes take up to 10 seconds to open.

 This is on an AMD 3950 CPU with a high speed 2TB NVME drive.

Version 11.16

 I rebuilt my Launchbox setup from scratch last night and am still seeing issues where some playlists take a while to open.  The weird thing is that at one point I had it working where 'All Games' would open right away, but after some theme/view changes, it went back to being slow again.

 I left bigbox running over night and checked it this morning.  'All Games' was still slow to open.  I closed bigbox and re-opened it.  Now 'All Games' opens instantly again.  The behavior seems really inconsistent.

 

edit: The 'Shooter' playlist takes 7 or 8 seconds to open still.  This is one I noticed was slow on my system.  Other playlists open instantly.  

 

edit2: I loaded bigbox again and have not made any changes.  'All Games' was slow to open again (10 seconds).  

 

edit3: I loaded bigbox yet again.  'All Games' now took 25 seconds to open.

edit4:  This appears to be some kind of caching/memory issue?  If I let bigbox sit idle, its memory usage keeps growing at about 2mb/s until it reaches a peak at about 2.5gb.  When it hit peak, "All Games" opened quickly, but memory usage suddenly dropped back to 500mb with the usual 2mb/s climb again.  "All Games" was slow again.

 I downgraded to a clean version 11.12, reimported my games and playlists appear to load fine now.  I am positive this issue was happening sometime before 11.16, but after 11.12.  

 11.16 did use more cpu, but memory usage seems about the same.  Also of note is that the Arcade platform (not category) shows all the games in it where with 11.16 it didn't show any.  I can use an "all games" image with the platform to make it useful in the playfield categories view I have as default.

  I didn't re-download any media, just moved it over from my old install folder.

 I need to make a backup of my 11.12 launcbox folders and then I will upgrade.  Once that is done (hopefully next day or so) I will test the playlist opening speed one more time.  If it's still slow (I think it will be), I will forward you what you are looking for.  I usually do a build on my main PC and then export it to my arcade PC.  The slowness was happening on both machines.

 Well, surprise surprise...  Now I can't reproduce the problem after updating to 11.17 (again).  Playlist opening speed is instant and I've tested it several times.

We did put some related performance improvements in for 11.17, so it may actually be a permanent fix. Let us know if you see it again.
