[mythtv-users] Load average in mythweb show 0.5 when at 99% during transcode/flagging etc

[Cory Zerwas]

Hello,

Well, this is kind of OT...  It's not really a percentage.  Think of it as
an average of how many tasks are executing at once on CPUs.  My explaination
isn't going to cover all the bases but think of it along these lines (from
what I understand, experts feel free to comment).  If I have a single
processor machine and a process is consuming all CPU this is in theory a
load of about 1.0, if I have a two processor machine and one process is
consuming all CPU on only one CPU it would be about 0.5.  Do you happen to
have a multi-core, XEON, or SMP system?
