Got some input on this. Heavy disk and/or network i/o seems to cause the pauses. Doing a copy over nfs(writing to disk), or using scp gives me 1-2 MB/s. If I boot plain rc4, I get full network speed(10-11 MB/s with nfs, 5-8 MB/s with scp). - 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/
