Slowness and angular errors

[etienne-napoleone]

When we exceeded a dozen nodes, the stats website became quite unresponsive. While the historical graph of block time is correct, the data are not 100% live which can let people think the chain is slow.
This error started popping up in the browser console also:

This is not present in devnet/testnet where the number of nodes are smaller and the interface snappier
