- No. I once configured a DECsystem 5810 with 256 MB of memory to use
- 80% buffer cache. It's not a configuration I would recommend, especially
- if you do lots of writes. I've regularly run 128 MB systems with 25%
- buffer caches and those have worked fine. You do have to watch how
- you use delay_wbuffers with a large cache.
