This should give us plenty of headroom for modest expansion of the loader. Steal 512KB more from system memory for heap instead of 256KB.

By default this is initialised to 16k, 1998-11-02T23:28:11Z Mike Smith msmith@FreeBSD.org 1998-11-02T23:28:11Z urn:sha1:af1f6e0673515936750cc5079ca5afd238ec925c and will bypass transfers for more than 8k. Blocks are invalidated after 2 seconds, so removable media should not confuse the cache. The 8k threshold is a compromise; all UFS transfers performed by libstand are 8k or less, so large file reads thrash the cache. However many filesystem metadata operations are also performed using 8k blocks, so using a lower threshold gives poor performance. Those of you with an eye for cache algorithms are welcome to tell me how badly this one sucks; you can start with the 'bcachestats' command which will print the contents of the cache and access statistics. * Extend the memory available for the heap from 256k to 512k. 1998-10-31T17:12:32Z Doug Rabson dfr@FreeBSD.org 1998-10-31T17:12:32Z urn:sha1:06feb69276c45157af7e9e5bbbf56d74cd77ebfe * Embed the stack into the bss section for loader and netboot.
