ACL (access control lists)

[sulekha]

Hi,


why it is said that enabling ACLs(access control lists) can reduce performance or do not enable ACL on file systems that holds system files, where traditional Linux permissions are sufficient?

Well, one could imagine that if you enable ACL it is just one more thing for the system to check and thus there will be a performance hit.

In reality, I do not notice a difference in speed or performance with SELinux active vs inactive (SELinux is basically a system wide ACL). I seriously doubt you will notice any performance difference with any modern hardware after enabling ACL (just my 2c).

What is it that you are reading ? Why do you need ACL ?
