Hello  
We have performed load testing using JMeter for 100 users. For the first few requests everything works fine but after sometime Gateway timeout error is encountered.Please refer to screenshot: [http://imageshack.com/i/pnnrBje4p](http://imageshack.com/i/pnnrBje4p)

In the beginning, same APIs run successfully but later the very same APIs return this error (504 Gateway Timeout Error).

We have configured mattermost with AWS server .  
**AWS server details:**  
**Web Server Instance**  
Instance Size: C3 2X large  
**RDS Server Instance**  
db.m4.large

Hi Ajita,

Hard to tell what your problem is without some logs from the Mattermost server. Also are you using a machine running Nginx as we suggest or are you using another proxy like ELB?

For our next release (3.5 November 16) we are doing a big push on performance. If your considering using Mattermost at a scale above 10000 users I would evaluate our current master build. You can find that here: [https://releases.mattermost.com/mattermost-platform/master/mattermost-enterprise-linux-amd64.tar.gz](https://releases.mattermost.com/mattermost-platform/master/mattermost-enterprise-linux-amd64.tar.gz)

We are currently working on a document to help people setup Mattermost at large scale. Some suggestions from that document:

Modify your /etc/init/mattermost.conf to be:

```auto
start on runlevel [2345]
stop on runlevel [016]
respawn
limit nofile 50000 50000
chdir /home/ubuntu/mattermost
setuid ubuntu
exec bin/platform

```

Modify your ulimits on your proxy and Mattermost machines. (by editing /etc/security/limits.conf)

```auto
ulimit -n 65536 65536
ulimit -u 8192 8192

```
