[AdministrativeConnectionProperties] Section
| Property Name | Supported In | Restrictions | Description |
| 0 <= Length <= 255 | Server administrator's email address | ||
| MaxConnections | 0 < Value <= 1024 | Max # of open administration connections | |
| Port | Port to use for administration operations. WARNING: If you change the port # here you must also change the corresponding port # in webconfig.ini | ||
| QueueSize | 0 < Value <= 1024 | Max # of administration operations to queue | |
| ThreadPoolSize | 0 < Value <= 1024 | # of threads available for processing administration operations |
MaxConnections
MaxConnections determines the maximum number of web tier connections the server will accept. For MapGuide 2.1 and earlier on Windows, the total number of connections (administrative + client + site) must be no greater than 62 connections. On the 63rd connection attempt, the server will become unresponsive. For MapGuide 2.2 on Windows and all versions of MapGuide on Linux, the supported connection limit is greater than 500 connections.
To fully utilize all cores on a MapGuide server machine, there should be 1 administrative, 3 client, and 2 site connections per core. Assigning additional connections may reduce request queue lengths and better utilize server resources if longer delay features sources like WMS, WFS, and databases are used. For local on-disk feature sources like SDF and SHP, the 1/3/2 per core listed above will typically be sufficient.
QueueSize
The request queue size should be set to at leat MaxConnections - ThreadPoolSize. Setting the queue size too low could lead to request loss under heavy load.
ThreadPoolSize
To fully utilize all cores on a MapGuide server machine, there should be 1 administrative, 3 client, and 2 site threads available per core. Increasing the thread pool size further may reduce request queue lengths and better utilize server resources if longer delay features sources like WMS, WFS, and databases are used. For local on-disk feature sources like SDF and SHP, the 1/3/2 per core listed above will typically be sufficient.

CacheSize
The MapGuide Server uses schema and class definition information in many requests. Caching this information locally increases server throughput and increases the memory footprint. CacheSize controls how many objects the server will cache. If sufficient memory is available, the CacheSize should be set to the total number of feature classes visible from all feature sources.
DataConnectionPoolExcludedProviders
By default, SDF data sources do not use pooled connections. This allows read/write operations to occur. Some performance improvement can be obtained by enabling connection pooling for SDF and SHP. Note: Turning on connection pooling for SDF will make SDF unsuitable for FDO update operations. If temporary layers are constructed using SDFs, connection pooling must be disabled for SDF.
DataConnectionPoolSize
Pooled connections allows the MapGuide Server to reuse existing connections to FDO feature sources. Database connections are created once and reused for multiple requests. Typically, two connections per core is sufficient to obtain full utilization of the cores on the MapGuide Server. Please note: Many FDO providers maintain schema for each connection. This increases the memory footprint as more connections are opened.
DataConnectionPoolSizeCustom
Pooled connections can also be set on a per-provider basis. This can be used to increase the connection pool for specific providers, like databases, while leaving the other providers alone. See DataConnectionPoolSize for tuning considerations.

RepositoryCheckpointsTimerInterval
The repository checkpoints timer interval determines the time between successive Resource Service database checkpoints. While a checkpoint occurs, all database writes are suspended. This can lead to freezes in client UI interaction as the Web Tier waits for the Session Repository to accept writes. Reducing the checkpoint interval will increase the number of freezes that occcur in a given time interval and will also reduce the time per freeze. If the database checkpoint takes too long, some operations will timeout and users may experience unexpected behaviour. Please note: Very large concurrent user loads are needed before checkpoint freezes become noticeable.
[SiteServiceProperties] Section
| Property Name | Supported In | Restrictions | Description |
| SessionTimeout | 0 < Value <= 86400 | Time duration in seconds for when an idle session is expired | |
| SessionTimerInterval | 0 < Value <= 2147483647 | ime interval in seconds for when the server checks for idle sessions |
SessionTimeout
The session timeout determines the maximum idle time for a session. Once the idle time has been reached, the session will be deleted from the session repository. The MapGuide Server keeps a portion of the session repository in memory and flushes least used pages to disk. A shorter idle time will delete sessions more rapidly and reduce page flushing. The page flush occurs during repository checkpointing.
SessionTimerInterval
The session timer interval controls how often the session repository is checked for idle sessions. This value should be set to 1/2 or 1/3rd of the session timeout to ensure that ide sessions are removed on a regular basis.

FailoverRetryTime
For a single Web Tier and MapGuide server pair use 1. For a load balanced configuration with multiple MapGuide servers use 60. Values other than 1 will cause a delay when re-establishing a connection with the Web Tier after restarting a MapGuide server.
[AdministrativeConnectionProperties] Section
| Property Name | Supported In | Restrictions | Description |
| MaxConnections | The maximum allowed concurrent connections for this port. | ||
| !Port | The port to use for administrative operations. If you change the port # here you must also change the corresponding port # for the server configuration file. |
MaxConnections
The default values in the table below are applicable for a typical user load and a single web tier process space connected to a quad core server. In MapGuide 2.1, the MapGuide server on Windows can only support 62 open connections. Heavy user loads on Windows may create multiple web tier processes and exhaust the available connections with the default settings. MaxConnections may need to be reduced under these circumstances. For MapGuide 2.2 and later, the MapGuide server can support more than 500 connections.
| Connection Type | Platform | Default Value | Tuning Considerations |
| Administrative | MapGuide 2.1 Windows | 2 | Reduce to 1 if server becomes unresposive under heavy load |
| Client | MapGuide 2.1 Windows | 12 | Reduce to 6 if server becomes unresposive under heavy load |
| Site | MapGuide 2.1 Windows | 6 | Reduce to 3 if server becomes unresposive under heavy load |
| Administrative | MapGuide Linux (all versions) MapGuide 2.2 Windows | 2 | Set to #of cores on server machine |
