It could only help in the case you have several CPUs but something prevents ksocklnd to spread the load over them. > Is there threading anyplace? Yes, ksocklnd spawns separate socknal_sd thread for each CPU/core that you have. There are two algorithms of spreading the load - you can play with enable_irq_affinity modparam flag. > Or is faster cpu the only way out? > I believe you either need faster CPU or faster system bus. If slow system bus isn't your case, increasing number of CPUs also will do.
