[zfs-discuss] Max_Payload_Size (was Re: 7-disk raidz achieves 430 MB/s reads and...)

2008-03-13 Thread Anton B. Rang
Be careful of changing the Max_Payload_Size parameter. It needs to match, and be supported, between all PCI-E components which might communicate with each other. You can tell what values are supported by reading the Device Capabilities Register and checking the Max_Payload_Size Supported bits.
