RhoConnect Benchmarks

Note, these numbers reflect synchronization performance using the rhoconnect bench utilities (see the rhoconnect/bench folder for more information).
We will be adding more results as we test across different server environments.

Prepare bench applications for running on server #1

Go to rhoconnect/bench directory and configure benchapp application:

sudo cp -R benchapp /var/www/
cd /var/www/
sudo mkdir benchapp/public
sudo chown -R www-data:www-data benchapp/

Do the same for blobapp bench:

sudo cp -R blobapp /var/www/
cd /var/www/
sudo mkdir blobapp/public
sudo chown -R www-data:www-data blobapp/

Edit Nginx configuration file, set server_name and root properties to public DNS server name and bench application public folder respectively. After restarting server make sure that bench application is running by visiting its web console, i.e. :

http://server_dns_public_name/console/ 

How to execute bench scripts on server #2

Before running bench scripts you need configure bench application settings properly.

Edit rhoconnect/bench/benchapp/settings/settings.yml and set redis and syncserver properties:

:development:
  :licensefile: settings/license.key
  :redis: server_ip_address:6379
  :syncserver: http://server_dns_public_name:80/api/application/

Do the same for blobapp settings.yml file.

Then from rhoconnect/bench directory execute run_cud_script.sh and run_blob_script.sh scripts respectively.

Multi-core Amazon EC2 server environments

Configuration

Server configurations:

  • Large (m1.large, 2 cores, 7.5GB memory)

  • Extra Large (m1.xlarge, 4 cores, 15GB memory)

  • High-CPU Extra Large (c1.xlarge, 8 cores, 7GB memory)

  • Platform – Basic 64-bit Amazon Linux AMI 2011.09 (Red Hat based)

Software environment:

  • Nginx 1.0.6

  • Ruby 1.8.7 (2011-02-18 patchlevel 334) [i686-linux], Ruby Enterprise Edition 2011.03

  • Passenger 3.0.9

  • Redis 2.2.14

  • Rhoconnect 3.0.0

All above software are installed on servers by executing the following commands:

sudo yum install make patch gcc-c++ zlib-devel curl-devel pcre-devel readline-devel openssl-devel
sudo rpm -i rhoconnect-3.0.0.noarch.rpm

Tested bench application (benchapp)

  • Simulates creating multiple objects

  • 100 concurrent users

  • 1 device per user

  • 20 object dataset

  • each object has 7 attributes

Prepare bench application for running on servers

  1. Go to rhoconnect/bench directory and configure benchapp application:

    sudo cp -R benchapp /opt/nginx/html
    cd /opt/nginx/html/benchapp
    sudo /opt/rhoconnect/bin/bundle install —without=test development
    sudo mkdir public
    sudo chown -R nginx:nginx /opt/nginx/html/benchapp
    
  2. Edit ‘/opt/nginx/conf/conf.d/rhoconnect.conf’ file and point root entry to /opt/nginx/html/benchapp/public directory:

    server {
    listen      80;
    root  /opt/nginx/html/benchapp/public;
    passenger_enabled on;
    }
    
  3. Start redis and nginx servers:

    sudo /etc/init.d/redis start
    sudo /etc/init.d/nginx start
