For industry wide statistics, something like https://www.cambridgeassociates.com/wp-content/uploads/2018/... is pretty good. All returns there are gross, not net, but they show top quartile funds returning 15-20% gross over the last decade, varying a bit year to year.

For specific fund performance, I don't know of anything public. Most of the big names have had some funds with >20% returns, usually as they get bigger those get harder to maintain.
