[Differential] [Commented On] D1986: Teach lagg(4) to change MTU

hrs added a subscriber: hrs. hrs added a comment. It is true that this LOR is driver-specific but calling SIOCSIFMTU after acquiring a lock in lagg ioctl is not always safe. Change of lladdr suffers from the same situation and it was solved by using an asynchronous task queue to update

ixl 40G bad performance?

Hi, I'm running a few simple tests on -CURRENT with a pair of dual-port Intel XL710 boards, which are seen by the kernel as: ixl0: mem 0xdc80-0xdcff,0xdd808000-0xdd80 irq 32 at device 0.0 on pci3 ixl0: Using MSIX

Re: ixl 40G bad performance?

i would look at the following: - c states and clock speed - make sure you never go below C1, and fix the clock speed to max. Sure these parameters also affect the 10G card, but there may be strange interaction that trigger the power saving modes in different ways - interrupt moderation

Re: ixl 40G bad performance?

Hi, in order to eliminate network or hardware weirdness, I've rerun the test with Linux 4.3rc6, where I get 13.1 Gbits/sec throughput and 52 usec flood ping latency. Not great either, but in line with earlier experiments with Mellanox NICs and an untuned Linux system. On 2015-10-19, at 17:11,
