thank you for your response mdahlman Wrote: I have about 300 reports in my "Generated Reports" folder. It displays in about 4 seconds. I don't think JS attempts to read all of the reports into memory. What sort of performance are you seeing as "slow"? How does it compare with performance of other folders? Can you test with JS 3.7 as well? Regards, Matt when a user wants to display content of the folder and clicks on the folder it takes about 1min to finish this operation. there are 20 reports, each 20mb. i have no problem with other folders, there are only jrxml files. i haven't tested it wiht 3.7, it is production server so it is not so simple.
