Do you think that folks need to have the log items for each request 
interleaved with other items?  I'm thinking here about the extremes of load 
(4,000,000 hits/day --> ~50 hits/sec --> 750 log entries/sec, assuming 15 
entries per request.)  Four million hits/day is a lot now, but it won't be 
much in a year.

We've actually started work in the other direction, where the server might 
accumulate the logging information for some user-specified period of time 
(several seconds, typically), and dump the information in a single I/O 
operation.  You can still do all of the fancy stuff about displaying 
response times, etc., but they'll be a few seconds behind the curve.
