I've been running Linux for more than ten years, but I'm pretty new to OpenSolaris.
We want to put up a new website for videos, and we'd like a rock-solid stable system, so I've been looking at OpenSolaris - and primarily OpenIndiana. We have a Dell PowerEdge 2900 with eight processing cores and 16GB Ram for this project. My question is this: When I have Linux loaded on this system, and I do a "top" command, it shows something like 99.3% idle most of the time. When I have OpenIndiana, OpenSolaris, or Nexenta Core 3.0 on it, it shows more like 80% idle, with the majority of the remaining 20% listed as "kernel". Is it normal for OpenSolaris to take up so much of the CPU just to run, compared to Linux? Is this likely to affect the overall performance of the server, compared to Linux, if we put this server in production with OpenIndiana? I'm wondering if we'd be better off using Linux on this server? Any advice / feedback would be appreciated.
