Hi

This module will take many resources of CPU and RAM. If you do not set a limit to this function, your CPU and RAM will be taken up and it's hard to say that the router could work when scaning files. I think tplink has to make a choic between stablity and function.

Think about buying a Synology NAS to meet your requirements. 

Hi WiFi Stealer,

Thank you for your useful comments.

TP-Link have been looking into this issue for me. Their R&D people seem to believe that they can increase the amount of files I'm seeing from 7,500 to around 30,000 without there being a big hit on performance. I'll have to see how the beta firmware goes if or when they make it available to me. I can always reverse out the change if, like you say, the router starts to fail in its primary function of being a wi-fi broadband router.

Regards
