Is there a different configuration of the xcf file between the 3.00 3.10 versions?
If there was, it would be in the Upgrade Guide section of the documentation
http://4js.com/online_documentation/fjs-gas-manual-html/#gas-topics/c_gas_migrate_310.htmlThis sounds like an issue that should be managed through your support contact. Please ensure you give the correct version information, you said "GBC 3.10", GBC has its own version numbering scheme and is upto 1.00.53.
I do wonder if you have moved from using GAS 3.00 using the GWC-HTML5 snippets, to using GAS 3.10 with GBC. Long story short, the Application Server is doing less work whilst the Browser is doing more work with this move, and so I am wondering how much work is the Browser being asked to do (simple or complex forms) and what processing capabilities does the Zebra TC200 device have. If so the first test might be to compare speed running browser on small device vs browser on desktop, and then in desktop using Dev Tools to throttle and simulate low or mid tier mobile.
