Ever faced performance problems when exporting large volumes of data using Publish Channels? Does these symptoms look familiar - "my export was working fine when I was doing in batches of 100 or 200 - but when I started doing 500 records at a time the performance degraded!" Maybe its a good time to look at your Publish Channel setup. Turning off “Retain Mbo's” is one such setup in the channel that might help you get better performance out of your data export.
