Additional index for properties table

I take a look on my MYSQL Server and it seems that there is no index on
the oc_poperties table!

owncloud use the following command:

SELECT * FROM 'oc_properties' WHERE 'userid' = '<USERID>' AND
'propertypath' = '<PATH>'

it takes up to 2 seconds to execute this command!

after I add:

CREATE INDEX USER_PATH ON owncloudusr.oc_properties (userid,
propertypath)

it takes 0.2 seconds!

Best Regards
