I have just read the lwn comments. They have pointed out that the NT server was setted to use only 1GB of memory, so my last example of "biased tunning" doens't apply. Sorry for my error :-).
Any way I would be glad to know which is the maximum amount of RAM kernel 2.2 can handle. Thank you all, Paulo -- Paulo José da Silva e Silva <[EMAIL PROTECTED]> Ph.D. Student in Applied Math. University of São Paulo - Brazil http://www.ime.usp.br/~rsilva "May the code be with you" :-)
