Mantrid - HTTP load balancer from Epio
Mantrid is the HTTP load balancer used for Epio. It is designed with high availability and simplicity in mind: it is configured at runtime with JSON over HTTP and can temporarily hold open connections while backend servers restart. It monitors bandwidth and connection statistics and is ideal for serving large numbers of hostnames.
It trades some raw speed for flexibility, but is still designed to be fast. Its aim is to have latency of no more than 10ms, and have no more than a 10% reduction in throughput.
