Hi, I've been testing some software in a server virtual environment and I've noticed I get a huge amount of CPU usage on the Interrupts process.

My question is, how does this relate to the virtual hardware platform as the rate is allot lower in a real system. Some how the hypervizor scheduler works hard to over come this problem but not as well as on real hardware does.

Obvious things are high I/O and disk access but this application mostly just sits and works in memory allot.

If anyone has experienced the same, please let me know. thanks in advance
