Queue with many records and bad performance

Hi,

We have a problem that messages sent from an ECC system to SAP PI are always sent to the same queue. This queue is acting extremely slow after a while and has a lot of waiting records ( >1000). These messages are starting a BPM in SAP PI. After a while it takes minutes per record.

What can I do to improve the performance of messages from our ECC system to SAP PI.

Kind regards,

Maarten van IJzendoorn
