Brian Behlendorf abd8610cd5 Add L2ARC tunables 
The performance of the L2ARC can be tweaked by a number of tunables, which
may be necessary for different workloads:

     l2arc_write_max         max write bytes per interval
     l2arc_write_boost       extra write bytes during device warmup
     l2arc_noprefetch        skip caching prefetched buffers
     l2arc_headroom          number of max device writes to precache
     l2arc_feed_secs         seconds between L2ARC writing
     l2arc_feed_min_ms       min feed interval in milliseconds
     l2arc_feed_again        turbo L2ARC warmup
     l2arc_norw              no reads during writes

README.markdown

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!

$ ./configure
$ make pkg
