I haven't noticed any performance impact, but I picked up a recent version of ansible-relayor that enables the sandbox by default and it broke two of my relays running Debian 8.9 under OpenVZ with kernel version 2.6.32. Given the old kernel version I'm not exactly surprised, but enabling the sandbox by default does cause those two relays to fail to start.
If anyone is interested, the relevant log lines (with debug enabled) look like this:
sandbox_getaddrinfo(): (Sandbox) getaddrinfo succeeded. sandbox_getaddrinfo(): (Sandbox) getaddrinfo failed. sandbox_getaddrinfo(): (Sandbox) getaddrinfo succeeded. install_syscall_filter(): Bug: (Sandbox) failed to load: -22 (Invalid argument)! (on Tor 0.3.0.9 ) tor_main(): Bug: Failed to create syscall sandbox filter (on Tor 0.3.0.9 ) main process exited, code=exited, status=1/FAILURE
I logged this on the tor bug tracker: https://trac.torproject.org/projects/tor/ticket/23090
