I'm testing Lenovo Helix to work with Microsoft Dynamics CRM. A strange issue has occured during test: when the tablet is working on WiFi, MSD performance can be a bit sluggish. In the airplane mode, MSD gets a boost performing way better than when connected to the internet.
I have been browsing the internet for a while now and cannot find any explanation on this but found nothing. Don't know if the issue is tablet-related or MSD-related.
Thanks in advance for your help.

I am assuming you are using MS CRM through outlook, not the browser.
So when you switch of your internet connection and have the offline client installed, it will revert to offline mode. Which can be faster because of:
1. Data is not traveling over the network, only to a local web server on your machine
2. The amount of data/plugins etc. you have localy is probably much lower, based on how you setup your offline filters
Try pinging the MS CRM server and see what the latency is. If it's higher than say 100ms this might be the cause of performance degredation. Of course it depends a lot on the implementation. If you have a lot of client side scripting / SL web resources which communicate with the server, the connection speed (latency) between you and the server will matter a lot.
In general if you are having performance issues with the Helix check what speed the CPU is running at. This machine, among other issues, has a tendency to get stuck at 0.6-0.8 GHz and not get any higher, which has a massive impact on performance.
This especially happens when you allow it to run out of battery juice (like keeping it at sleep for a longer period).
Solution is to do a hard reset of the tablet and the base through the small holes near the power ports.

Yes, your assumption is correct. We are working via Outlook.
Problem is, that we test disconnected to the Internet but with WiFi running and somehow switching to Airplane mode (WiFi off) boosts performance. Very weird situation.
