Breathtaking performance

It was the same story when we used DivX 7, iTunes 8.1 and CyberLink PowerProducer 5 as they clearly are not able to make effective use of multiple cores.

In iTunes, we converted 458 MP3 files - totalling 2GB - to AAC format, and in DivX we worked with six AVI movies that also totalled 2GB. In Power Producer we recoded a single 350MB AVI file to DVD format. We can illustrate the lack of efficient threading as a single Xeon that is converting files in DivX 7 uses all eight cores at about 50 per cent load. Installing a second Xeon drops the load to 30 per cent on each core.
