I have not had any > performance issues using selinux in RHEL 5, RHCS included. Results will probably vary depending on what components you need, and what versions you run. For us, SELinux incurred a 30% overhead with GFS file operations. That was on CentOS 5.2 or 5.3, can't remember which. (We're in the middle of an upgrade to 5.5, but haven't started migrating to GFS2.) But don't take my word for it, or anyone else's... always benchmark your own application. -Jeff -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
