Guidelines for acceptable performance
Notes
Search indexes
One per SSP
Maximum of 20 per farm
Office SharePoint Server 2007 supports one content index per SSP. Given that we recommend a maximum of 20 SSPs per farm, a maximum of 20 content indexes is supported.
Note that an SSP can be associated with only one index server and one content index. However, an index server can be associated with multiple SSPs and have a content index for each SSP.
Indexed documents
50,000,000 per content index
Office SharePoint Server 2007 supports 50 million documents per index server. This could be divided up into multiple content indexes based on the number of SSPs associated with an index server.
Content sources
500 per SSP*
This is a hard limit enforced by the system.
Start Addresses
500 per content source*
Alerts
1,000,000 per SSP
This is the tested limit.
Scopes
200 per site
This is a recommended limit per site. We recommend a maximum of 100 scope rules per scope.
Display groups
25 per site
These are used for a grouped display of scopes through the user interface.
Crawl rules
10,000 per SSP
We recommend a maximum 10,000 crawl rules irrespective of type.
Keywords
15,000 per site
We recommend a maximum of 10 Best Bets and five synonyms per keyword.
Crawled properties
500,000 per SSP
These are properties that are discovered during a crawl.
Managed properties
100,000 per SSP
These are properties used by the search system in queries. Crawled properties are mapped to managed properties. We recommend a maximum of 100 mappings per managed property.
Authoritative pages
200 per relevance level
This is the maximum number of sites in each of the four relevance levels.
Results removal
100
This is the maximum recommended number of URLs that should be removed from the system in one operation.
