A GEOM cache can speed up read performance by sending fixed size
read requests to its consumer. It has been developed to address the problem of a horrible read performance of a 64k blocksize FS residing on a RAID3 array with 8 data components, where a single disk component would only get 8k read requests, thus effectively killing disk performance under high load. Documentation will be provided later. I'd like to thank Vsevolod Lobko for his bright ideas, and Pawel Jakub Dawidek for helping me fix the nasty bug.
