One example demonstrates the use of an MBean server to manage and monitor a node in a distributed system, and the other example acts as the managed node.

This topic provides guidelines for tuning vSphere virtualized environments that host Apache Geode deployments.
Without tuning, Geode can suffer a performance drop in virtual environments, including the VMware vSphere virtual platform.

You can make configuration adjustments to improve the UDP multicast performance of peer-to-peer communication in your Geode system.
Before you begin, you should understand Geode [Basic Configuration and Programming](../../basic_config/book_intro.html). See also the general communication tuning and UDP tuning covered in [Socket Communication](socket_communication.html) and [UDP Communication](udp_communication.html#udp_comm).

Multicast installations require more planning and configuration than TCP installations. With IP multicast, you gain scalability but lose the administrative convenience of TCP.

TCP automatically adjusts its speed to the capability of the processes using it and enforces bandwidth sharing so that every process gets a turn. With multicast, you must determine and explicitly set those limits.

For peer-to-peer communication, you can manage socket use at the system member level and at the thread level.
The conserve-sockets setting indicates whether application threads share sockets with other threads or use their own sockets for distributed system member communication. This setting has no effect on communication between a server and its clients, but it does control the server\u2019s communication with its peers or a gateway sender's communication with a gateway receiver. In client/server settings in particular, where there can be a large number of clients for each server, controlling peer-to-peer socket use is an important part of tuning server performance.

The more frequently a get fails to find a valid value in the first cache and has to try a second cache, the more the overall performance is affected.
A common cause of misses is expiration or eviction of the entry. If you have a region\u2019s entry expiration or eviction enabled, monitor the region and entry statistics.

You have several options for handling slow members that receive data distribution. The slow receiver options control only to peer-to-peer communication between distributed regions using TCP/IP. This topic does not apply to client/server or multi-site communication, or to communication using the UDP unicast or IP multicast protocols.
Most of the options for handling slow members are related to on-site configuration during system integration and tuning. For this information, see [Slow Receivers with TCP/IP](slow_receivers.html).

Cache timeout properties can modified through the gfsh `alter runtime` command (or declared in the `cache.xml` file) and can also be set through methods of the interface, `org.apache.geode.cache.Cache`.
To modify cache timeout properties, you can issue the following `gfsh alter runtime` command. For example:

In systems with distributed-ack regions, a sudden large number of distributed-no-ack operations can cause distributed-ack operations to take a long time to complete.
The `distributed-no-ack` operations can come from anywhere. They may be updates to `distributed-no-ack` regions or they may be other `distributed-no-ack` operations, like destroys, performed on any region in the cache, including the `distributed-ack` regions.

You have several options for preventing situations that can cause slow receivers of data distributions. The slow receiver options control only peer-to-peer communication using TCP/IP. This discussion does not apply to client/server or multi-site communication, or to communication using the UDP unicast or multicast protocols.
Before you begin, you should understand Geode [Basic Configuration and Programming](../../basic_config/book_intro.html).

Geode processes communicate using TCP/IP and UDP unicast and multicast protocols. In all cases, communication uses sockets that you can tune to optimize performance.
The adjustments you make to tune your Geode communication may run up against operating system limits. If this happens, check with your system administrator about adjusting the operating system settings.

The number of sockets available to your applications is governed by operating system limits.
Sockets use file descriptors and the operating system\u2019s view of your application\u2019s socket use is expressed in terms of file descriptors. There are two limits, one on the maximum descriptors available to a single application and the other on the total number of descriptors available in the system. If you get error messages telling you that you have too many files open, you might be hitting the operating system limits with your use of sockets. Your system administrator might be able to increase the system limits so that you have more available. You can also tune your members to use fewer sockets for their outgoing connections. This section discusses socket use in Geode and ways to limit socket consumption in your Geode members.

When you determine buffer size settings, you try to strike a balance between communication needs and other processing.
Larger socket buffers allow your members to distribute data and events more quickly, but they also take memory away from other things. If you store very large data objects in your cache, finding the right sizing for your buffers while leaving enough memory for the cached data can become critical to system performance.

Geode supports TCP KeepAlive to prevent socket connections from being timed out.
The `gemfire.enableTcpKeepAlive` system property prevents connections that appear idle from being timed out (for example, by a firewall.) When configured to true, Geode enables the SO\_KEEPALIVE option for individual sockets. This operating system-level setting allows the socket to send verification checks (ACK requests) to remote systems in order to determine whether or not to keep the socket connection alive.

This property controls the number of threads that can be used to establish new TCP/IP connections between peer caches. The threads are discarded if they are idle for 60 seconds.

If your application exhibits unacceptably high latencies, you might improve performance by modifying your JVM\u2019s garbage collection behavior.
Garbage collection, while necessary, introduces latency into your system by consuming resources that would otherwise be available to your application. You can reduce the impact of garbage collection in two ways:

You configure JVM memory settings for the Java application by adding parameters to the java invocation. For the cache server, you add them to the command-line parameters for the gfsh `start server` command.
- JVM heap size\u2014Your JVM may require more memory than is allocated by default. For example, you may need to increase heap size for an application that stores a lot of data. You can set a maximum size and an initial size, so if you know you will be using the maximum (or close to it) for the life of the member, you can speed memory allocation time by setting the initial size to the maximum. This sets both the maximum and initial memory sizes to 1024 megabytes for a Java application:

You can make configuration adjustments to improve multicast and unicast UDP performance of peer-to-peer communication.
You can tune your Geode UDP messaging to maximize throughput. There are two main tuning goals: to use the largest reasonable datagram packet sizes and to reduce retransmission rates. These actions reduce messaging overhead and overall traffic on your network while still getting your data where it needs to go. Geode also provides statistics to help you decide when to change your UDP messaging settings.

For secure transmission of sensitive information, like passwords, you can encrypt credentials using the Diffie-Hellman key exchange algorithm.
This encryption applies only to client/server authentication - not peer-to-peer authentication.

Authentication lends a measure of security to a distributed system
by verifying the identity of components as they connect to the system.
All components use the same authentication mechanism.
