[EP-tech] Re: load throttling strategy

I confess I just throttled the server: in httpd.conf add

StartServers    2
MinSpareServers 1
MaxSpareServers 1
MaxClients    128

(I put mine right next to where I defined the user & group for the server)

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which has hit it's "out of date" time so rebuilds.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has also hit its "out of date" time, so spawns ANOTHER page rebuild.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 ?
