What’s the load of each PPPoE server?, or how many can I have in one router?

I’m currently working with a CCR1072, I know that it can handle a lot of PPPoE connections but I don’t know if it’s using just one PPPoE server, i have around 14 VLANs and I want to use a PPPoE server with a different segment for each one, so in total 14 PPPoE servers, do you think it could handle around 2,000 PPPoE connections split between those servers? would the extra amount of PPPoE servers be a huge load for the CCR1072 to handle?
