PI performance issue for a single Interface
In a PI 7.0 system we are experiencing very bad performance for a single interface. It is sending daily a 1MB payload message and it takes about 10 seconds to process (this is OK), but on fridays a bigger set of records is sent, about 45MB payload. It takes more than 2 days to process the message!!!
I have been doing some research and I see that the bottleneck is in the Integration Engine. I have compared it with other interfaces that sent huge messages as well, and I only see a point that I don´t understand. While other messages, of about 43MB payload (read it in SXMB_MONI, parameter <SAP:MessageSizePayload>) has a message size of 15MB in field MSG_SIZE of table SXMSPMAST, the problematic interface, with a <SAP:MessageSizePayload> parameter of 45MB, has SXMSPMAST-MSG_SIZE of 19MB.
Can somebody explain me the relationship between these two sizes and and idea on what can I do in order to reduce MSG_SIZE?
Thanks in advanced for your help
