GNOME Music Should No Longer Be So Sluggish
Being frustrated by slowdowns in GNOME Music where it could take just 15~20 seconds to load albums, Stavracas made use of Sysprof for profiling the music player and discovered that there were tons of asynchronous calls happening in parallel. He ended up placing a limit on the number of parallel lookups allowed by Music and that in turn has allowed for an improvement by around 73%, at least on Georges' system.
More details for those interested via this blog post. Look for the improvement to be part of GNOME 3.26.
