# Performance
|
|
|
|
SFTPGo can easily saturate a Gigabit connection on low end hardware with no special configuration, this is generally enough for most use cases.
|
|
|
|
For Multi-Gig connections, some performance improvements and comparisons with OpenSSH have been discussed [here](https://github.com/drakkan/sftpgo/issues/69), most of them have been included in the main branch. To summarize:
|
|
|
|
- In current state with all performance improvements applied, SFTP performance is very close to OpenSSH however CPU usage is higher. SCP performance match OpenSSH.
|
|
- The main bottlenecks are the encryption and the messages authentication, so if you can use a fast cipher with implicit messages authentication, such as `aes128-gcm@openssh.com`, you will get a big performance boost.
|
|
- SCP protocol is much simpler than SFTP and so, the multi-platform, SFTPGo's SCP implementation performs better than SFTP.
|
|
- Load balancing with HAProxy can greatly improve the performance if CPU not become the bottleneck.

### Hardware specification
|
|

**Server** ||
|

CPU| Ryzen5 3600 |

RAM| 64GB 2400MHz ECC |

### Test configurations
|
|
|
|
- `Baseline`: SFTPGo version 0.9.6.
|
|
- `Devel`: SFTPGo commit b0ed1905918b9dcc22f9a20e89e354313f491734, compiled with Golang 1.14.2. This is basically the same as v1.0.0 as far as performance is concerned.
|
|
- `Optimized`: Various [optimizations](#Optimizations-applied) applied on top of `Devel`.
|
|
- `Balanced`: Two optimized instances, running on localhost, load balanced by HAProxy 2.1.3.
|
|
- `OpenSSH`: OpenSSH_7.9p1 Debian-10+deb10u2, OpenSSL 1.1.1d 10 Sep 2019
|
|
|
|
Server's CPU is in Eco mode, you can expect better results in certain cases with a stronger CPU, especially multi-stream HAProxy balanced load.
|
|
|
|
#### Cipher aes128-ctr
|
|
|
|
The Message Authentication Code (MAC) used is `hmac-sha2-256`.

### Optimizations applied
|
|
|
|
- AES-CTR optimization of Go compiler for x86_64, there is a [patch](https://go-review.googlesource.com/c/go/+/51670) that hasn't been merged yet, you can apply it yourself.
|
|
|
|

|
|
timeout connect 10s
|
|

|
|
timeout queue 30s
|
|

|
|
