Hosting #82

Disable some web server access logs

Heavy traffic can lead to web server access logs becoming very large. It is therefore recommended that you disable all except those that are essential. By limiting the number of events registered in the application’s log, we avoid writing to the disk, which minimizes CPU consumption and the storage space needed.

Design #95

Adapt sounds to the listening environment

Audio files can be large and use up lots of bandwidth. It is therefore important to minimize their size. Choose one of the 3 formats that cover the 3 largest platforms (Windows, Mac OS X and Linux):
- MP3 (MPEG-1 Audio Layer 3) - AAC (Advanced Audio Coding) - Vorbis

These formats apply fine-tuned compression algorithms that greatly reduce file size.
