We have recently been focusing on improving performance and scalability...Take a look at these visualisation graphs for GaianDB networks of up to 520 nodes! - These were running on 13 blades, each having 4 logical CPUs
The next release of GaianDB (1.02) expected this month will contain many optimisations. In particular, we have looked at minimising CPU and memory consumption of GaianDB nodes. We have also improved the node discovery and connection algorithm to minimise network diameter and hence query times across the network from any node.
For reference, simple query times across a network of 52 nodes were initially taking 89ms *before* optimisations...[Read More]
