Quite a few when you consider how many entries are in a log. However,
speed was not my primary concern.
Server stats are and will remain a local issue no matter how fast the
Internet grows. There are several reasons for this:
1. The log file is not directly accessible to the web -- some local processing
must be performed before it is made available.
2. Machine usage is generally dependent on local users (and their work hours)
and its generally considered "nicer" to perform large remote accesses
during that site's off-peak hours. Thus, as a webmaster, I need to
evaluate usage at my site in terms of how it effects local usage during
local peak hours.
3. The log file is intended to assist humans trying to maintain their
own server, and (except in the UK), all humans think in local time.
This is particularly notable at the begin/end of each month when the
log file is truncated by date.
4. Local events (such as power failures, lightning storms, earthquakes,
due dates for final projects, etc.) occur in local time and, if they
have some effect on the server, it's easier to match the effect with
the event if the log reflects local time.
Having said that, it's certainly possible that some people will want to
publish their log in GMT. However, since I anticipate that to be an
extremely small percentage of web sites, it makes more sense to have
those sites convert their log to GMT (using any number of analyzers)
rather than to require all other sites to convert from GMT to local time.
