Console performance is slow and sometimes times out due to wildcard on a query.
Lack of disk space, high segment count, high data retention or other hardware related factor can affect the performance. This solution is specific for performance issue due to wildcard on a query.
On any query, using asterisk ( * ) at the beginning of the query will cause performance issue. Please only use wildcard(s) anywhere on the query other than at the beginning of the text.
