### No RAFT slowing you down
It might seem strange to tout the absence of something as a desirable feature,
but this is in fact a very important point! Garage does not use RAFT or another
consensus algorithm internally to order incoming requests: this means that all requests
directed to a Garage cluster can be handled independently of one another instead
of going through a central bottleneck (the leader node).
As a consequence, requests can be handled much faster, even in cases where latency
between cluster nodes is important (see our [benchmarks](@/documentation/design/benchmarks/index.md) for data on this).
This is particularly usefull when nodes are far from one another and talk to one other through standard Internet connections.
