Hello,
I monitored very big network with great tool is Observium.
But I have issue with "BGP All session" page :
When I navigate on this page, the load time is >20 seconds.
I have not the issue with "All ports" page.
We have >22k BGP sessions and >1300 Remote ASN.
The generation time displayed in bottom righ is between 1 and 2 sec.
After some time, I think understand the problem :
It's not generation issue, but navigator issue with javascript.
The left pan load <0.5sec with first BGP list.
