Very slow transcoding at very high CPU usage

[arie01]

Hi,

I have a question about transcoding.

I have a Panasonic 2011 model and I’m using the Panasonic Viera (No DivX) profile.

I’m using a Toshiba Satellite Pro 750S as my media server. That laptop has 4GB of RAM and a Quad Core i5 2520M CPU that runs at 2.5GHz with turbo of up to 3.2GHz (if I’m not mistaken).

Every time I transcode files, mostly MP4 or MKV at 720p and 6-channels audio, it takes forever to transcode them and all my CPU cores are constantly at 99-100%.
The CPU fan is screaming and blowing intense heat from the opening.

Before I started using 6-channel audio, it was doing the same thing, very slow transcoding at 99-100% CPU usage.

I run Windows 7 Pro x64 and my files are local. The max fps I’m getting is 27-29 and the minimum is between 5-7.

I recently increased priority to Very High after reading that someone said his CPU is never above 80%, but this also has no effect on my system.

Is there anything I can do to improve transcoding speeds?

Thank you,
