Optimize: Article List Load Performance having Distance Calculation and Thumbnail load (MongoDB, Ruby, Android)


on my Android App on Home View I have a list of articles. Each article has - amongst others - distance (from user location to article location) and thumbnail shown.

Currently load time for 250 articles takes like 10 seconds.

I need an expert for optimizing code logic/structure or overall approach.

Technologies in use:

- MongoDB

- Ruby / RoR

- Android

If interested please send a conceptional draft of your solution design to be implemented, incl. headlines for technology to be used and basic data flow.

Also, please make sure you are 100% available and dedicated to this project only.

Looking forward for your reply.

Thanks and kind regards

José Dias
