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.

The command output lists the following:

swapfile dev swaplo blocks free
... ... ... 788384 ...

Paragraph 6 refers to the number of blocks as "688384" instead of "788384."

states "the ext3 filesystem has writes scheduled every 5 seconds as opposed to the
30-second delay associates with ext3" - one of those "ext3" mentions should be ext2.

AUTHOR: Valid: second "ext3" should be an "ext2."

the book reads:
"When the first packet in a TCP connection is sent from the server ..."
It should be:
"When the first packet in a TCP connection is sent to the server ..."

i.e. change "from" to "to"

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....
