When the load is 100% you can't handle any more transactions than the max.
We have seen Ethereum and Bitcoin run into these problems where they need to handle more transactions than the blockchain allows. When this happens you get a backlog of transactions waiting to be confirmed.
You basically get a traffic jam on the the blockchain. And unless you pay a high fee to get in front of the line you will just have to wait it out untill your transaction clears.
STEEM does not have this problem because we are very far from maximum load. No traffic jams on the steem blockchain.
Wow then this is an exceptionally good news and to think we are already this much and have achieved this much on steemit while carrying out transactions with only 0.14% load on the network is simply mind blowing
