Cognos BI 10.2.2
Windows 2012 R2 server
After upgrade from Cognos BI 10.1.1 to Cognos BI 10.2.2 the creation of PDF reports takes several minutes, when it before take only seconds.
HTML reports are as fast they were in the older version of Cognos BI.
If you remove the pictures in the report, then the PDF file is created fast.
Copy all the images to the Report BI server, in old version the images that are in reports are on the Cognos BI Gateway server only. Now it is recommended to have them on all BI servers.
Update all servers to have the pictures in the folder .. \samples\images.
The PDF creation looks locally for the pictures at first, before going to the gateway.
