middle 1st paragraph,

It says "It's probably safe to assume that a 5-MIPS CPU will outperform a 100 MIPS CPU, ...". Clearly it had to be a 100 MIPS CPU outperforming a 5 MIPS CPU.

Last paragraph on the page

The author indicates that TLB stands for 'transaction lookaside buffer', however, as I remember from my computer architecture class, and as a search on Google (search terms 'TLB lookaside buffer') confirms, it actually stands for 'translation lookaside buffer' instead. AUTHOR: Valid.

1st paragraph

In the paragraph titled "The maxusers parameter" this formula is given: 7 x maxusers + 9C According to Sun's documentation, the correct formula is (17 x maxusers) + 90 That is, 17 not 7, 90 not 9C. This is confirmed by the value of 34,906 given at the bottom of the page. As an aside, IMO use of parens would be nice to disambiguate the order of the operation for users who not sure about operator precedence, etc. AUTHOR: Correct -- this is a typesetting error....
