While desktop Dynamics CRM installations make use of fast machines with (nearly) unlimited storage, mobile devices are severely limited in this respect.
You typically get numbers such as:
- RAM Memory: ~1GB RAM (iPhone5/6, high end Android devices approach 3GB).
Low RAM values (~500MB or less) will negatively impact the database speed or, for example, the download speed.*)
- Storage memory: It’s here where the database will be located.**) Today’s mobile devices typically offer 4+ GB of storage memory, which is – by proper planning – enough. We’ll return to the subject later.
- Speed: It is difficult to bring any generally applicable numbers. Instead, here are a few numbers that measure activities done by Resco MCRM:
Database writes on a decent mobile device are 5-10x slower than the same operations done on a rather aging 2GHz W7 desktop. And it can go even worse, for example Xml parsing (used in communication with CRM server) is ~100x slower.***)
- Internet speed: We cannot give any generally applicable statements here. Speed of 3G networks vary between 144kbps to 4+Mbps, 4G networks are even faster.****)
