According to www.mpg123.org: ---snip--- Needed computing power A recent test (GNU/Linux OS) with 0.60-beta2 showed 3% to 4% CPU usage =20 on decoding high quality VBR MP3 with a pentiumII laptop with 366MHz, =20 while a pentium 100MHz can easily handle two mpg123 instances in =20 realtime (plus the mixing daemon that works on decoded data). Michael said once upon a time Plays Layer 3 in stereo on an AMD-486-120Mhz or (of course) a faster machine= . Just for info: mpg123 plays an average 128bps stream, with about 66% =20 in full quality on an AMD 486-133MHz machine. ---snip--- Bye, Alexander. --=20 Ferengi Rule of Acquisition #239: =09 Never be afraid to mislabel a product. =09=09-- ST:DS9, "Body Parts" http://www.Leidinger.net Alexander @ Leidinger.net: PGP ID =3D B0063FE7 http://www.FreeBSD.org netchild @ FreeBSD.org : PGP ID =3D 72077137
