[Freeswitch-users] mod_v8 vs mod_lua overhead?

Hi - I need to do an sql query with some logic and manipulation, and then route a call. I think it's a bit much to do with mod_odbc_query and the dialplan, so I'll be using mod_lua or mod_v8. Does anyone have information about the overhead about running a script in either language? I know mod_lua has been the goto scripting language for low overhead, but how does the newer mod_v8 perform? I'd rather use javascript, but only if there isn't a significant performance difference. Thanks, -Avi Marcus
