Running command omnirpt -report host -host server.domain.local -tab in cell server with a big list of clients, omnirpt takes minutes for finish. If you run the same command in the same server just leaving cell and client entries it takes seconds.
Command is reading cell_info file taking a lot of time when this is not necessary, host name is being determined with command syntax.
Open support case and request hotfix QCCR2A71548
