I have a 128MB V2.1 news server running INN, with the default (10%?) buffer 
cache
size:
real mem = 134217728
avail mem = 130039808
buffer cache = 13258752

Has anyone got any info on whether it is worth increasing the buffer cache
on an IO-bound news server with 128MB RAM?  If so where is this set?  I have 
looked in the kernel config file and in boot.default with no luck.
