Performance issue - BO Publisher 6.5

Question

Post Author: fionas
CA Forum: Publishing
Hi,
We are using publisher 6.5 to burst customized BO reports to users in PDF format. We have five full client reports which are configured in five different publications. Each publication will send the customized report in PDF format and each publication will send more than 1000 reports at a time. We run all the five publications one by one using publisher (BA). So every time we burst more than 5000 reports using publisher 6.5. The publisher sends the first 600 to 700 reports quickly of each publication. After that the performance of publisher comes down and it takes very long time to send the remaining reports. So we need your advice on this.
Why the publisher performance comes down after sending some number of reports? How to improve the performance of the publisher? (As a work around we split each report into two, so that each report will send approx 500 reports and we run the publisher ten times (5 X 2) instead of running it only for five times. This requires extra effort)

Hi,
How is the database server operating system coping in terms of CPU load and memory? and what is the db data cache hit ratio in ST04?
I would look into the following things, network configuration between database and central instance, and the load on the DB server cpu load/memory and possibly the most important the DB2 memory and configuration instead of focusing on the SAP application server in case of high DB times.
Please be aware of the fact that tables in upgrade from 4.6C to ECC increase from about 30000 to 60-70000 and db tuning is the most likely explanation for your problems.
