After upgrading to 7.3.2, Jetty should be configured based upon your current JBoss configuration. All customer configurations for Jetty are located in the jetty/base folder.

During upgrade or a new installation, the following files will be created for you in Jetty:

Amongst several open source application servers available in the market, Jetty is preferred mostly because of its faster loading time, smaller memory footprint, superior performance and higher data throughput. Feb 12, 2020 Jetty web server offers us a way to deploy a web archive located anywhere in the file system by us creating a context file for it. This way, even if our WAR file is located on a desktop or we have chosen to keep it in jetty-app/target where Maven places the package, we can just create its context file inside $JETTYHOME/webapps.

• jetty/base/etc/installation.properties
• jetty/base/etc/perc-ds.xml
• jetty/base/etc/perc-ds.properties

The installation.properties file will contain settings for HTTPS if you had HTTPS set up prior on the JBoss installation. Jetty will exclusively start with HTTP until you enable HTTPS.

Starting Jetty through Command line

Patch 732_20171004 updated The StartJetty.sh script for linux to be able to safety run as root, or the user that owns the Rhythmyx root folder. It will show an error if run as any other user. It will also check to make sure the instance is not already running in another shell or as a service.

Windows users should ensure that the current JBoss install is not already running and that any other instance is not already running.

Windows

Linux

Jetty will always run as the owner of the Rhythmyx base folder since Patch 732_20171004. Installing the service will change ownership of the contained files and folders to ensure they are consistent.

To find who is the owner in user, group format:

Next cd into the {RHYTHMYX_HOME}/jetty directory

Installing the Rhythmyx Jetty Service and disabling the old JBoss service

Installing the Jetty Service will allow Rhythmyx to start via service rather than manually, and allow it to startup when the system boots up.

Ensure that Rhythmyx is not already running. Additionally, the old Rhythmyx service should be disabled so that it does not start automatically on Startup. Otherwise the Jetty Service will conflict with the old Rhythmyx JBoss service.

Disabling the old Rhythmyx JBoss service on Windows

Disabling the old Rhythmyx JBoss service on Linux

Since Patch 20171007 The service install will warn if there is already a JBoss service installed. You can automatically remove this service with the cleanupJBoss argument to the install-jetty-service.sh

Installing the new Rhythmyx Jetty service on Windows

Execute the following batch script to install the jetty service: install-jetty-service.bat install

Installing the new Rhythmyx Jetty service on Linux

Starting and stopping the Jetty service

After installing the Jetty service, it will automatically start every time the system is booted.

Windows

To start and stop the Jetty Service on Windows, use the same install batch file to start and stop Jetty, using the following parameters:

Linux

You will usually have to logged in as root or use the sudo command and have permissions to start and stop the services.

Ubuntu/Debian/RHEL6

To start and stop the Jetty Service on Ubuntu, Debian, and RHEL6 use the following commands:

CentOS 6

To start and stop the Jetty Service on CentOS6, use the following commands:

RHEL7/CentOS 7

To start and stop the Jetty Service on CentOS 7 and RHEL7, use the following commands:

Removing all JBoss related Files

Now that JBoss is disabled and Jetty is up and running, you may now remove all JBoss related files.

Please review Removing JBoss from install, and have Rhythmyx exclusively use only Jetty on what files should backed up and what files can be removed.

Introduction

Jetty 7 and Jetty 8 are now EOL (End of Life)

THIS IS NOT THE DOCUMENTATION YOU ARE LOOKING FOR!!!!!
All development and stable releases are being performed with Jetty 9 and Jetty 10.
This wiki is now officially out of date and all content has been moved to the Jetty Documentation Hub

Direct Link to updated documentation: http://www.eclipse.org/jetty/documentation/current/high-load.html

Configuring Jetty for highload, albeit for load testing or for production, requires that the operating system, the JVM, jetty, the application, the network and the load generation all be tuned.

Load Generation for Load Testing

• The load generation machines must have their OS, JVM etc tuned just as much as the server machines.
• The load generation should not be over the local network on the server machine, as this has unrealistic performance and latency as well as different packet sizes and transport characteristics.
• The load generator should generate a realistic load:
  • A common mistake is that load generators often open relatively few connections that are kept totally busy sending as many requests as possible over each connection. This causes the measured throughput to be limited by request latency (see Lies Damned Lies and Benchmarks for an analysis of such an issue.
  • Another common mistake is to use a TCP/IP for a single request and to open many many short lived connections. This will often result in accept queues filling and limitations due to file descriptor and/or port starvation.
• A load generator should well model the traffic profile from the normal clients of the server. For browsers, this if mostly between 2 and 6 connections that are mostly idle and that are used in sporadic bursts with read times in between. The connections are mostly long held HTTP/1.1 connections.
• Load generators should be written in asynchronous programming style, so that limited threads does not limit the maximum number of users that can be simulated. If the generator is not asynchronous, then a thread pool of 2000 may only be able to simulate 500 or less users. The Jetty HttpClient is an ideal basis for building a load generator, as it is asynchronous and can be used to simulate many thousands of connections (see the Cometd Load Tester for a good example of a realistic load generator).

Operating System Tuning

Both the server machine and any load generating machines need to be tuned to support many TCP/IP connections and high throughput.

Linux

Linux does a reasonable job of self configuring TCP/IP, but there are a few limits and defaults that that are best increased. These can mostly be configured in /etc/security/limits.conf or via sysctl

TCP Buffer Sizes

These should be increased to at least 16MB for 10G paths and tune the autotuning (although buffer bloat now needs to be considered).

Queue Sizes

net.core.somaxconn controls the size of the connection listening queue. The default value of 128 and if you are running a high-volume server and connections are getting refused at a TCP level, then you want to increase this. This is a very tweakable setting in such a case. Too high and you'll get resource problems as it tries to notify a server of a large number of connections and many will remain pending, and too low and you'll get refused connections:

The net.core.netdev_max_backlog controls the size of the incoming packet queue for upper-layer (java) processing. The default (2048) may be increased and other related parameters (TODO MORE EXPLANATION) adjusted with:

Ports

If many outgoing connections are made (eg on load generators), then the operating system may run low on ports. Thus it is best to increase the port range used and allow reuse of sockets in TIME_WAIT:

File Descriptors

Busy servers and load generators may run out of file descriptors as the system defaults are normally low. These can be increased for a specific user in /etc/security/limits.conf:

Congestion Control

Linux supports pluggable congestion control algorithms. To get a list of congestion control algorithms that are available in your kernel run:

If cubic and/or htcp are not listed then you will need to research the control algorithms for your kernel. You can try setting the control to cubic with:

Mac OS

Windows

Seriously???

Network Tuning

• Intermediaries such as nginx can use non persistent HTTP/1.0 connection. Make sure that persistent HTTP/1.1 connections are used.

JVM Tuning

• Tune the Garbage Collection
• Allocate sufficient memory
• Use the -server option

Low Resource Limits

Must not be configured for less than the number of expected connections.

Thread Pool

It is very important to limit the task queue of Jetty. By default, the queue is unbounded! As a result, if under high load in excess of the processing power of the webapp, jetty will keep a lot of requests on the queue. Even after the load has stopped, Jetty will appear to have stopped responding to new requests as it still has lots of requests on the queue to handle.

For a high reliability system, it should reject the excess requests immediately (fail fast) by using a queuewith a bounded capability. The capability (maximum queue length) should be calculated according to the 'no-response' time tolerable. For example, if the webapp can handle 100 requests per second, and if you can allow it one minute to recover from excessive high load, you can set the queue capability to 60*100=6000. If it is set too low, it will reject requests too soon and can't handle normal load spike.

Below is a sample configuration:

Configure the number of threads according to the webapp. That is, how many threads it needsin order to achieve the best performance. Configure with mind to limiting memory usage maximum available.Typically >50 and <500.
