Audacity flatpak very slow to start compared with snap or AppImage #127

Open IgnacioJPickering opened 1 year ago

IgnacioJPickering commented 1 year ago

Bug description

I'm running Ubuntu 22.04 with GNOME and the Audacity flatpak (from flathub) is very slow to start (around x5 times slower than the corresponding snap). AppImage shows same behavior.

Steps to reproduce

Install and run the audacity flatpak with:

flatpak install flathub org.audacityteam.Audacity
flatpak run org.audacityteam.Audacity

Expected behavior

Startup should be roughly as fast as snap

Actual behavior

Startup time is 5x slower

Audacity Version

latest stable version

Operating system

Linux

is the slow start because of the plugin loading or is it something "invisible"?

the following is outdated (and somewhat wrong)

for me it is the plugin loading that takes way longer than the system's (manjaro) audacity version (they also seemingly share the same path to store configuration and plugins in ~/.audacity-data and so overwrite eachother)

after some investigation and observing, the problem with long plugin load times are:

  • the same plugins are again downloaded (even though they exist in /app/extensions)

  • plugin downloads happen from http://plugin.org.uk, which is slower for me compared to the systems audacity http://calf.sourceforge.net

  • more plugins are bundled / downloaded than the system's audacity

I will debunk a myth:

NO PLUGIN IS DOWNLOADED

if you mean the startup from my comment, then yes, no plugin is downloaded (no network activity, my mistake), though then why does it list duplicate entries (and checks duplicately) once from /app/extensions and once plugin.org.uk?

hfiguiere commented 12 months ago

because one is LADSPA and the other is LV2. LV2 uses URI as an identifier. It has nothing to do with any sort of dowload.

IgnacioJPickering commented 12 months ago

How can I check if this has anything to do with plugins? It seems to hang for a couple of seconds with no visible dialogues before starting. Is there a way to start the flatpak in a more verbose mode to debug possible issues? I'm having a similar issue with AppImage. Both apt and snap start way faster.

IgnacioJPickering commented 12 months ago

Also, both the appimage and the flatpak seem to do something funny with the microphone tray icon. It flashes in and out of existence a couple of times before the app starts. No such thing happens with the apt / snap

IgnacioJPickering commented 12 months ago

I've updated to reflect the fact that the appimage presents the same behavior
