Hit counter persistent variables

Thanks for the suggestion. I don't really want to go to that extent and 
I'd wonder if updating a database would just slow the static files down. 
What I had in mind is just incrementing a variable. I suppose I could 
write a simple module that maintains a few in memory varibles. Just 
wondered if there was an easier way.

Maybe write a log format that just adds a single char for each hit. Then 
later I can find hit count by checking the length of that log file? And 
a cron once an hour that stores the file length in another file and 
deletes the log so it repeats. But is it possible to just write one char 
to a log file? Maybe log format like,

log_format hits 'x';

Just an idea. Would that be very fast?
