I on the other hand am having no problems with slow connections. However, this is with very little load on the system. Here is one such trace: http://www.cybsft.com/testresults/2.6.9-rc1-bk4-Q7/latencytrace4.txt I do have a couple of new traces that seem to be related to transmitting data, I think. They are here: http://www.cybsft.com/testresults/2.6.9-rc1-bk4-Q7/latencytrace2.txt http://www.cybsft.com/testresults/2.6.9-rc1-bk4-Q7/latencytrace3.txt kr - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
