BI4 Launchpad - Browsing for documents is extremely slow when working over VPN

Our Environment Details:
4.1 SP6.6
Win2008
2 Tomcat servers, 6 App servers (located in Michigan)
URL for Launchpad and CMC sits behind an F5.

We have a lot of users who access the BI4 Launchpad from different locations. The performance is very different, depending on the location. We have users complaining specifically about modifying a report by inserting a logo on a document. When they click 'Browse' button on the insert logo box, they have extreme slowness when navigating to the corporate network share. The same users do not have issues opening "My Computer" and clicking on that same network share - it is only extremely slow when launching browse through the internet explorer launchpad session.

Scenario 1: Staff member located at the data center where servers are located, launching BI4 Launchpad from internet explorer from local PC. Clicks the browse button within the modify report and has no performance issues.

Scenario 2: Staff member located remotely from the data center where the servers are located, dialed into the corporate network through VPN. Clicks browse button within the modify report and has extreme slowness. Almost unusable from this perspective. That same remote user can go to "My Computer" and browse that network share with no issues.

Scenario 3: Staff member located remotely from the data center where the servers are located, dialed into the corporate network through VPN. Logs onto a Citrix server and launches Internet Explorer to bring up the Launchpad. When modifying a report and clicking the browse button to locate an image, they do not experience this same slowness when attempting to browse the network share.

The easy answer to this is to send all remote users to Citrix servers to perform their work, but the idea behind having a web page is that you should be able to access it anywhere without the hardware overhead.

Has anyone else experienced this? I realize part of this is a network latency issue, but are there any tips/tricks you have found that will help this particular situation?

I don't have personal experience but I have heard this from others - could it be WAN issues? See http://blue-coat.ru/images/stories/docs/SAP_Business_Objects_Explorer_Demo_for_Blue_Coat_WAN_Op.3.pdf

Can your VPN users use "Image form address" instead of "Images from file"?

The downside from "Image form address" is that all images to be used would need to be copied and placed in the

<installed drive:>\Program Files (x86)\SAP BusinessObjects\SAP BusinessObjects Enterprise XI 4.0\images folder 1st.

The best person to respond to your queries here is your Infrastructure guy. You may need consider everything from your Network bandwidth, Number of Hobs to be travelled for every request for your each scenario, etc.

We talked with our network person and they basically said that anyone working remotely through the VPN, they can't guarantee any level of performance because everyone has different internet providers, speeds, etc. I was more looking to find out if anyone else had experienced this, and if they found a way around it.

Also, interestingly enough, when I modify the report to use HTML rather than Applet, it actually improves the speed drastically. I am not a user of the application, just a technical support person (and a new one, at that), but it seems like these two different methods (applet vs. html) access the data differently.

when you use Applet - a bunch of jar files need to be downloaded to your local machine, so that your local Java can run them, connect back to BOE etc... when you use HTML panel, everything is in the browser and back on the server that's why it looks faster.

And your network person just gave you a canned answer meaning "i don't have time to deal with this".

HTML is lacking some functionality than Applet version. If the expert webi report developers, then the user may need to use applet version than the casual user.
