[EP-tech] Re: load throttling strategy


I bet he's suffering the problem I had: Google loads a 'view' page, which has hit it's "out of date" time so rebuilds. In the mean time, another httpd catches the next google page load, which has also hit its "out of date" time, so spawns ANOTHER page rebuild.

It very quickly ramps up, and WILL swamp the server... and WILL crash the server.

Which issue are you trying to solve by introducing such a delay?

Hi,

does anyone have an easy way to throttle eprints website crawlers ?

I’m wondering is something as a short delay for each ePrint accessed -
the delay being proportional to the current load ?  That’s perhaps a
little blunt but might it be very easy to implement ?
