As a platform owner, you have to make sure your producers (ex. Lyft drivers) are incentivised enough and keep producing.
Withouth enough production from your producers your scalability and even your survival as a marketplace will bleed.
There are in general three reasons why producers get incentivized:
1) They earn money
2) They establish reputation - fame
3) They have fun
As long as one or more of the three above elements exist in your platform, users will be strongly incentivised to adopt and remain on your platform.
There are several other inorganic ways you can incentivise producers, like for example offering a signup bonus for newcomers.
In regards to managing performance, if what you mean is curating the best from the rest, that's where algorithms get in game. Review mechanisms are the most common way and in fact a very effective one, since it allows the community to rate the performance of each of the producers.
If by "manage performance" you mean if you can control your producers in terms of how much or how well they produce, you simply can't. That's if you are a traditional marketplace and you are just the provider of the space and the tools for producers and consumers to correlate.
On the other hand, if your marketplace pre-curates the producers, as a platform you most probably have already set some standards those producers should follow.
Hope that helps
