What I found is that if I limit to 250KB/s I can run 4 simultaneous DL but if I raise the limit to 300KB/s I loose connection. I can run unlimited with 3 connections seeing DL at 500+KB/s. Let me know if you need stack traces running in different scenarios.
My current set up is.

Asus A8V Delux

AMD 64 X2 3800+ Over clocked to 2.55GHz Benchmarked and stress tested stable. MB temp 28C CPU temp 32C with LW running DL at 400KB/s avg. CPU usage between 0% & 3%

2 GB corsair ram PF usage 352 MB LW Debug 86,000K

eVga nVidia 6200 256 MB

2 – Fujitsu U320 74 GB SCSI hard drive

1 – WD 120 GB hard drive

Comcast Cable 750KB/s Down 45KB/s Up
Marvel Yukon 88E8001/8003/8010 PCI Gigabite Ethernet Controller,

I do not know that all of this is needed but what the hell is a test without a few stats
