Some settings,…

• The IIS AppPool Identity needs the correct permissions via group assignement

• Setting of Counters.Enabled set to true • Setting of Counters.InstanceName (only if more than one instance on a server) • Setting of the HealthMonitorInterval • Setting of Sitecore.Tasks.CounterDumpAgent

Caution: Difference between Counters for Sitecore 7 and for Sitecore 8!

Sitecore Counters


Key Counters

Memory • Available Bytes • Committed Bytes

Processor • % Processor Time

Physical Disk • % Disk Time • Avg. Disk Queue Length

Network Interface • Bytes Total/sec • Current Bandwidth • Output Queue Length

System • Processor Queue

Length


Use performance counters to check warning signs

• Memory: Committed Bytes is creeping up long term • Processor: % Processor Time is above 75% long term and System: Processor Queue Length is above 10 • Physical Disk: % Disk Time is above 50% long term and Avg. Disk Queue Length is above 2 • Network Interface: Bytes Total/sec shows utilization is above 25% and Output Queue Length is above

SQL: Check SQL Server Index Fragmentation Level

1. Dramatic increase in CPU usage. 2. Performance degradation on queries. 3. Performance degradation on database writes. 4. Dropped connections to the database server. 5. Slow performance of renderings. 6. Slow performance of the Sitecore client tools — Desktop,

Content Editor, and so on

Symptoms


4. Auto Shrink Property Set To False

SQL Settings: Database Properties

3. Auto Close Property Set To False

1. Compatibility Level Set To SQL Server 2008 (100)

Inability to run scripts to improve performance

Longer times required connecting to the database.

Performance degradation.

2. Recovery Model Set to Simple

Performance degradation during recovery intervals

There are 4 main settings to improve performance:

Symptoms:


IIS Settings: HTTP Response Headers

Symptoms: 1. Constant high load times for requested pages. 2. Poor performance.


IIS Settings: Content Compression

Symptoms: 1. Constant high load times for requested pages. 2. Poor performance.


Sitecore Cache Settings:Tuning Sitecore Caches

Symptoms · Limited amount of memory to caches. · Frequent eviction of caches due to limited memory. Slow page rendering performance

Sitecore Recommendations:· If you have a 64-bit system, Sitecore recommends to disable cache limit.


Sitecore Cache Settings:Tuning Sitecore Caches

Symptoms · Poor solution performance. · Excessive server load. Decreased system capacity

Sitecore Recommendations: Set initial values: Tune cache values: Sitecore recommends that the Sitecore database cache size(s) is between 70% and 80% of their MaxSize, without seeing constant fluctuations to the Delta value.


Sitecore Cache Settings:Prefetch Cache


Cacheable — The Cacheable property defines whether or not the presentation component should be cached, regardless of what the VaryBy properties are set to.

Sitecore Cache Settings:Configuring Output Cache

VaryByData — Set to true for components that generate different output when used with different data sources.

VaryByDevice — Set to true for components that generate different output when used with different devices

VaryByLogin — Set to true for components that generate different output for an authenticated vs. an unauthenticated user. Note, the layout engine treats all anonymous users as a single authenticated user. o

VaryByQueryString — Set to true for components that generate a different output when different query string parameters are passed in.

VaryByUser — Set to true for components that generate different output for different users. Note, to avoid excessive memory usage only use VaryByUser on solutions with a relatively small number of users.

Sitecore allows developers to define output cache settings in three places:

VaryByParm — Set to true for components that generate a different output when different rendering parameters are passed in.


Symptoms · Slow performance during publishing. · Slow performance during indexing.

Sitecore Settings: Check Database Cleanup Agents

Sitecore Recommendations:· Sitecore recommends that the scheduling frequency be enabled by setting it to a value greater than 00:00:00. ·The default value for the frequency = 00:05:00 Cleanup agents for the History, PublishQueue, and EvenQueue be configured to have an interval greater than 00:00:00. The default value for the frequency = 00:05:00 and the default for the intervals = 04:00:00.


Sitecore Settings: Disable Showing Number of Locked Items

Symptoms · Dramatic performance degradation during loading the Experience Manager. ·

Sitecore Recommendations:· Set WebEdit.ShowNumberOfLockedItemsOnButton setting to false!
