[GLLUG] How much can I host?

[Seth Bembeneck]

Php is used quite a bit along with mysql. I don't know how many KB per day
and number of hits is pretty low.

What I want to do is to provide hosting on a case by case base, keeping an
eye on things and then not accepting any more clients when it looks like I'm
reaching my limit.

I just check top and it was hovering between .3 and 1.6, but I noticed that
it was top that was generating the additional cpu usage.

Any ways, thanks for the replies..
Seth

The content that you want to host makes the difference.  Are you hosting 
static HTML?  Images?  Linux mirrors (lots of large tarballs)?  PHP? 
Database backend?  How many hits per day?  KB per day?  Many, many, many 
factors play into this.

PHP/Perl/etc will require a substantially more powerful server than 
static HTML and images would in a hit-for-hit comparison; although, on a 
low traffic site nearly any machine could handle the load.

If the hard drive light is on all the time or if top reports CPU usage 
hovering at 1.0, if it takes a long time to get a page to load, etc.

This should be fine for most applications.

I don't really think you can "overload" bandwidth, but you could max out 
your connection's upstream capabilities.  Try installing webalizer or 
similar web traffic analyzer that reports average KB served/hour and 
other such stats.  You can calculate from those stats if you're 
consistently at your connection limits.

Unless you're doing _tons_ of dynamic content, I'd say it's just about 
impossible under normal conditions to overload a 400MHz web server with 
384k outbound; a 386 could flood that connection without trouble.

Absolutely.
