SHOUTcast network design & tweaking?

Does anyone have some good tips for designing or tweaking a SHOUTcast server, relay and/or client?

I am currently running a SHOUTcast and having skips (not buffering) on the stream. The source is a 1.1GHz/128MB/WinXP-Pro streaming 24kbps & 128kbps streams to 100Mbit/OC3 relays. The computer is hooked directly into a modem with a 384Kbps/MMDS business-class broadband line.

I am a fairly computer/network-literate individual and have stripped the XP computer for optimal performance and done multiple speed tests to my relays. The computer is running 0% CPU, 13% RAM and not dropping packets. The relays average 117ms round-trip (0% packet loss) and the farthest one is 9 hops away. The relay servers are also very under-utilized. What gives?

What output plug-in are you using. Try DirectSound (and yes, it does matter sometimes)

I tested a lot with shoutcast never had any real buffer probs.. but i noticed if you set up a local shoutcast and let you source stream to that one locally .. and you let the relays connect to your local shoutcast that it runs more smooth.. But don't know if that goes up for windows.. I run everything under linux ...

Thanks for the tip. I was planning on rebuilding one of my linux servers this weekend and doing what you had described.

One NIC external to broadband modem, one NIC internal to the source. Cast 24kbps & 128kbps to the linux shoutcast server and have the relays connect directly to that. This should lessen the source's burden when I want to provide more than one relay of each stream and I won't have to rely on Windows to do as much (cause that is when it seems to always break *grin*).

Just incase anyone was interested. I did just as my above post said and this cleared up my skip problems.
