'What is the difference between blockchain performance and blockchain scalability?

I really don´t get the difference between blockchain scalability and blockchain performance. Can some explain it to me?



Solution 1:[1]

Performance is an indication of the responsiveness of a system to execute any action within a given time interval, that means even if your blockchain is handling e.g. 5 transactions how is it handling it? while scalability is ability of a system either to handle increases in load without impact on performance or for the available resources to be readily increased.

Solution 2:[2]

When we talk about blockchain networks, I can suggest the following approach:

Performance is a rate at which useful data is added to the blockchain state.

Scalability is a maximal level of performance, security and decentralisation which target blockchain network can handle simultaneously.
