Hi
Thanks for a quick answer. My question was not how I could buy new hardware, as better hardware aren't allways the solution. The point is squeezing the power out of it. We've all seen before with benchmarks and the likes. After modifying some kernel parameters (/proc...), the system speeds up. Where's the human readable information about these parameters? Example: /proc/sys/net/core/netdev_max_backlog
This holds an initial value of 300. My NetWare experience tells me this could be something like NetWare's "Maximum packet receive buffers", the number of buffers allocated to buffer incoming packets from the network if the CPU load (or I/O) is too high. 1: Is this correct? 2: Where's the information telling me or others this? I know it's in the kernel code, but I can't understand that.
I hope this refined the question a little
Regards
Roy ------------
