We have a host template with 50 items and 10 triggers linked to 20.000 hosts approx.
When we create/modify/delete an item/trigger the process fails after a long while (>30mins) and huge memory/cpu usage.
With templates linked to less hosts (~100 hosts) everything works fine.
On 2.0.5rc1 rev ~32712 (included bunch of expected performance improvements):
We tried 2.0.5rc1 and it doesn't solve the problem:
we change an item in a template linked to 10.000 hosts and it takes approx 20 minutes which is too long for the user to wait.
we change an item in a template linked to 20.000 hosts and after a while (and huge cpu load) the process fails leaving just some hosts with the new added item.
