Subject [GitHub] cloudstack pull request: More VR performance!
Date Fri, 22 Jan 2016 10:29:58 GMT
Github user borisroman commented on the pull request:
    @DaanHoogland It improves performance due to fact firewall rules are only created (in
memory) once we expect a change. If for example a dhcp lease needs to be added, no firewall
rules will be build or changed.
    At first these were always executed:
    -    # Always run both CsAcl().process() methods		
     -    # They fill the base rules in config.fw[]		
     -    acls = CsAcl('networkacl', config)		
     -    acls.process()		
     -    acls = CsAcl('firewallrules', config)		
     -    acls.process()		
     -    fwd = CsForwardingRules("forwardingrules", config)		
     -    fwd.process()		
     -    vpns = CsSite2SiteVpn("site2sitevpn", config)		
     -    vpns.process()		
     -    rvpn = CsRemoteAccessVpn("remoteaccessvpn", config)		
     -    rvpn.process()		
     -    lb = CsLoadBalancer("loadbalancer", config)		
     -    lb.process()
    Now they are only executed if we expect change to the firewall rules.
    Less execution == more performance!
    Hope that clears up! :-)
