<font face="Comic Sans MS">Update. I tried encoding that video
again, but without the noapic and nolapic options. Handbrake was
encoding the video at between 35 and 40 frames per second. When I
rebooted and tried again with the noapic and noalpic options
enabled, Handbrake was encoding the same video with the same
settings at 17 to 20 frames a second. So is this something unique
to Handbrake or is there something else going on?<br>

First I checked /proc/cpuinfo which had 4790.8 as the value for
bogomips with noapic and nolapic in the grub2 config. I removed
these options and rebooted. This time I got 4791.43. So I'm
guessing that if I lost anything, it's not enough to matter. Am
I right?<br>

Thanks<br>

<p class="MsoNormal"><span style="font-family:"Comic Sans

Today I handbrake on a tv show episode I have on dvd. It's
a 30 minute show and Handbrake normally takes about 20
minutes to encode a 30 minute show. This time I noticed
the estimation of how long it would take hovered around 45
minutes. I then opened top and pressed 1 once it
started. It showed only cpu0. Shouldn't cpu1 also be
there? I looked around online and found that using the
noapic option in grub only allows one core of a multi core
processor to run. Is there any way to enable apic and
lapic if necessary without it causing my machine to lock up
again?<br>
<br>
Thanks<br>
