The reply tasklet is fast, but it's single threaded. After reply traffic saturates a single CPU, there's no more reply processing capacity. Replace the tasklet with a workqueue to spread reply handling across all CPUs. This also moves RPC/RDMA reply handling out of the soft IRQ context and into a context that allows sleeps.
Hi Chuck, I'm probably missing something here, but do you ever schedule in the workqueue context? Don't you need to explicitly schedule after a jiffie or so the code works also in a non fully preemptable kernel? -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
