[ixpmanager] route server prefixes views and memory usage

[Athanasios Douitsis]

Greetings to everyone,

I am sure many recipients on this list have clients that announce many
thousands of prefixes through their BGP peerings. At GR-IX, we have
observed that such clients can overwhelm the "Route Server Prefixes"
view with relative ease. This typically results in PHP throwing an error due
to the maximum allocated memory size being exceeded, and the entire page
comes back blank in the browser.

One obvious solution is to increase the PHP memory limit, but this does
not negate the fact that the above mentioned view and its corresponding
controller allocate memory in copious amounts. In case of multiple users
hitting that view simultaneously, this can be rather taxing on the
overall RAM usage.

I was wondering whether anyone else is aware of or is encountering
this problem. And, of course, whether there is some other elegant
solution that hitherto eludes us.

Kind regards,
