G'day Guys, Just a quick question.
From the tuning(7) man page:
Additionally, higher-end CPUs support 4MB MMU pages, which the kernel uses to map the kernel itself into memory, increasing its efficiency under heavy syscall loads. As this 4MB MMU pages have direct impact on TLB usage, it improves the performance significantly. However, I am wondering whether the same tuning can be applied to other parts of the kernel? e.g, can't we map mbuf clusters to 4MB MMU pages instead of 4K pages to improve the performance under heavy network load? Cheers kmb -- Something is wrong up on cloud # 9!
