Microsoft Defender vs. VLC: Which is causing MP3s to take 30 seconds to load?
A performance bug in VLC media player is causing MP3 files to take over 30 seconds to load, sparking debate about whether the issue lies with VLC or Microsoft Defender. Video game designer Jonathan Blow brought the problem to public attention on X (formerly Twitter), expressing frustration with the slow load times and criticizing the broader state of open source software. In response, Blow switched from VLC to Microsoft Media Player.
The exact cause of the delay remains unclear, with questions raised about potential involvement from Microsoft Defender’s scanning processes or other Windows system components. This incident has prompted wider discussion about performance and compatibility challenges in open source tools. Blow’s concerns highlight ongoing problems affecting mainstream open source applications and underscore the complexity of diagnosing performance issues in software ecosystems where multiple components interact, particularly when third-party security software may impact application performance.
