I want to know something about FreeBSD buffer cache implementation. 1) Where can I get the document about it?. 2) Which files in kernel src directory is concerned with it? 3) How can I enlarge the part for buffer cache in physical memory? 4) How can user process access the file in ufs filesystem through raw disk? Thanks in advance. Heo Sung-Gwan --- E-mail : heo@cslsun10.sogang.ac.kr
