There is an icon in the root of WDK apps called favicon.ico which is 300,318 bytes – rather rediculously large for an icon.
It’s in Documentum 6.5 through to 6.7 at least and seems to get loaded each time a new page is called putting a massive overhead on the network and slowing down TaskSpace and other apps built on WDK.
I put a ticket into EMC for this but also tried a number of tools online to shrink the icon from 300K to 1.4K and the best site was . This tool also provides a number of rendition options (which all looked pretty much the same so I picked the smallest filesize).
Another tool I tried online shrunk it to 61K which is still huge for an icon but definitely prodraw offers the most efficient solution.
