Firmware: 1.28.9052 MIPSR2-beta23 K26 USB Ext
I just noticed that the CPU usage goes through the roof when I'm downloading @ max speed. I only have a 16Mbit PPPoE connection, nothing too fast. When I download off usenet, tomato's web interface goes to a crawl and CPU usage is above 1. I tried telnetting in and running top -d1 and I see that SIRQ is taking up ~90% of the CPU when downloading.
Any ideas what is causing this?
Edit: I just tried some speedtest sites and it doesn't matter what/where I download from, as long as my connection gets maxed out, the SIRQ usage goes above 80%
