Indyco Explorer does a lot to minimize bandwidth requirements, but depending on your specific scenario it may be necessary to fine-tune the compression settings of your server.
Configure HTTP Compression in IIS
Please refer to this article to verify that the Static and Dynamic Content Compression featured are installed and enabled.
Enforce GZip Compression on JSON responses
As a further improvement, you can enforce GZip Compression on every JSON response to minimize the bandwidth required by Indyco Explorer.
Simply add the mime type “application/json” to the list of dynamic types under “system.webServer / httpCompression”.
Please note that this setting will impact every site deployed under your IIS server!
