It depends. I Mimiko's case it could help to lead to the right direction for further actions.

If I'd measure an average of 7 seconds to establish a connection to the MySQL server through the OTRS console I'd try to figure out if connections from the native MySQL client will provide similar results.
But to be honest - I'd not be concerned as long as the overall service quality is acceptable as long connection times don't need to be of consequence due to connection pooling of persistant connections.

Looks pretty unsuspicious to me so I'd not be worried about disk performance if I'd experience any overall service impairments.
