VACL capture cause performance impact?

Does anyone know whether VACL capture (apply VACL and configure capture port (switchport capture)), instead of normal SPAN (monitor session source/dest) can cause performance impact and/or any concerns?

Equipment: Catalyst 6509E with Sup720, MSFC3, and PFC3B

Hi,

  • VACLs are enforced in hardware; there is no performance penalty for applying VACLs to a VLAN on the Cisco Catalyst 6500 Series switches

Refer:

  • SPAN consumes too many switch and network resources to enable permanently. Exercise all possible care when enabling and configuring SPAN. The traffic copied by SPAN can impose a significant load on the switch and the network
