Alan Somers 2d8f72d76c zpool: speed up importing large pools (#11469) ... The ZFS_IOC_POOL_TRYIMPORT ioctl returns an nvlist from the kernel to a preallocated buffer in userland. Userland must guess how large the buffer should be. If it undersizes it, it must reallocate and try again. That can cost a lot of time for large pools. OpenZFS commit 28b40c8a6e set the guess at "zc.zc_nvlist_conf_size * 4" without explanation. On my system, that is too small. From experiment, x 32 is a better multiplier. But I don't know how to calculate it theoretically.
