# FAQ
|
||
|
||
## Why a new API gateway?
|
||
|
||
There are new requirements for API gateways in the field of microservices: higher flexibility, higher performance requirements, and cloud native.
|
||
|
||
## What are the differences between APISIX and other API gateways?
|
||
|
||
APISIX is based on etcd to save and synchronize configuration, not relational databases such as Postgres or MySQL.
|
||
|
||
This not only eliminates polling, makes the code more concise, but also makes configuration synchronization more real-time. At the same time, there will be no single point in the system, which is more usable.
|
||
|
||
In addition, APISIX has dynamic routing and hot loading of plug-ins, which is especially suitable for API management under micro-service system.
|
||
|
||
## What's the performance of APISIX?
|
||
|
||
One of the goals of APISIX design and development is the highest performance in the industry. Specific test data can be found here：[benchmark](https://github.com/iresty/apisix/blob/master/doc/benchmark.md)
|
||
|
||
APISIX is the highest performance API gateway with a single-core QPS of 23,000, with an average delay of only 0.6 milliseconds.
|
||
|
||
## Does APISIX have a console interface?
|
||
|
||
Yes, in version 0.6 we have dashboard built in, you can operate APISIX through the web interface.
|
||
|
||
## Can I write my own plugin?
|
||
|
||
Of course, APISIX provides flexible custom plugins for developers and businesses to write their own logic.
|
||
|
||
## Why we choose etcd as the configuration center?
|
||
|
||
For the configuration center, configuration storage is only the most basic function, and APISIX also needs the following features:
|
||
|
||
1. Cluster
|
||
2. Transactions
|
||
3. Multi-version Concurrency Control
|
||
4. Change Notification
|
||
5. High Performance
