[Spacewalk-list] Large Spacewalk Deployments?

[George]

 From experience with only a couple of 100 hosts and 'old' versions of 
spacewalk (say 0.8 or 0.9) the spacewalk server gets hammered if you do 
for example and upgrade of 1 (or more) packages on a group of several 
100 hosts at once ... (using osad so a "now" schedule) due to the fact 
it needs to receive the reporting that if the task failed or succeeded.
My webinterface was unreachable for like 30 minutes and load on the box 
was 70 or so ...
Note that at the time I was running it on dual core machine with 4G mem 
and oracle XE on the machine itself, so yes performance was not optimal.

Now I have a setup with 8 spacewalk proxies in several global regions 
and around a 100 machines connected, but not really tried any major 
deployments like I mentioned above (soon to be adding up to around 1000 
hosts).

I heard that for example puppet has some kind of backoff algorithm for 
this: if you get more requests than a certain max limit they will send 
the other requesters walking for a random time (also believe they have 
some kind of priority system, where a pushed update task gets priority 
over a random checkin from a server because the timer expired)

Planning to combine spacewalk with puppet for certain tasks like this ...

Regards,

G.
