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!

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
Environment Target Cache Value
Content Delivery Only
Web Prefetch 200 MB
Web Data 200 MB
Web Item 200 MB
Output (per site) html 100 MB
CMS Only
Master Prefetch 200 MB
Master Data 200 MB
Master Item 200 MB
CMS and Content Delivery on same server (master and web databases)
Master Data 200 MB
Environment / Target
Master Item 200 MB
Web Prefetch 150 MB
Web Data 150 MB
Web Item 150 MB
CMS and Content Deliver on same server (Live mode)
Master Data 300 MB
Master Item 300 MB
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 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. ·
Set WebEdit.ShowNumberOfLockedItemsOnButton
setting to false!
