Since I need to routinely compile program with library size up to 2MB, I was expecting the cache controller would give me some speed improvement while doing 'ar' and 'ranlib' repeatedly on the same library. However, after some thorough test, I notice that the cache controller doesn't seem to improve the I/O performance at all. Does Netbsd support VLB cache controller ? or I need some kind of driver ? Or does cache controller help at all? Any help would be appreciated P.S. I am using 0.8 with my 486 DX2 machine. with 4MB RAM installed on the cache IDE controller Jack
