Were you using 10 Gb or 40 Gb? 10 right? You meant 2 Gigabit/Gb above then right? If so, then no. I can get around 5 or 6 Gb for writes using the defaults and scst and ramdisks for the LUs. The only think I have had to do in some recent kernels is turn tcp_autocorking off. I am working on a patch for that now.
