Look for your current value of the kern.bio_transient_maxcnt and increase it by 4-8 times, using the same tunable. If this helps, fine. If not, disable unmapped i/o with the vfs.unmapped_buf_allowed tunable. Real solution is to convert geom classes like geli to use limited transient mapping windows to access the data, thus adding support for unmapped i/o to them.
