Bottleneck Analysis found a transaction waiting for I/O to complete on the long message (LGMSG) dataset. Check the IMS Logical Terminal workspace (Output Queued) to determine if there are a lot of messages queued to a particular LTERM. Dequeue these messages to reduce the utilization of the longt message dataset. Also, use the TRMQxx command to determine all LTERMS with queue counts. See the specific instructions for the LTOQ and LPOQ commands.
