(more) SharePoint 2007 figures & numbers

4 06 2007

Going a little bit further on the topic of limitatiosn that I blogged some days ago in the post SharePoint 2007 Maximum Limitations, I found some more details (and juicy ones ..) regarding limits and figures on Sharepoint 2007. It was sposted at technet.

 Here are some tables with the main figures:

The following table lists the recommended guidelines for site objects.

Site object

Guidelines for acceptable performance Notes Scope of impact when performance degrades
Site collection 50,000 per Web application Total farm throughput degrades as the number of site collections increases. Farm
Web site 250,000 per site collection You can create a very large total number of Web sites by nesting the subsites. For example, 100 sites, each with 1000 subsites, is 100,000 Web sites. The maximum recommended number of sites and subsites is 125 sites with 2,000 subsites each, for a total of 250,000 sites. Site collection
Subsite 2,000 per Web site The interface for enumerating subsites of a given Web site does not perform well as the number of subsites surpasses 2,000. Site view
Document 5 million per library You can create very large document libraries by nesting folders, using standard views and site hierarchy. This value may vary depending on how documents and folders are organized, and by the type and size of documents stored. Library
Item 2,000 per view Testing indicates a reduction in performance beyond two thousand items. Using indexing on a flat folder view can improve performance. List view
Document file size 50MB (2GB max*) File save performance is proportional to the size of the file. The default maximum is 50 MB. This maximum is enforced by the system, but you can change it to any value up to 2 GB. Library, file save performance
List 2,000 per Web site Testing indicates a reduction in list view performance beyond two thousand entries. List view
Field type 256 per list This is not a hard limit, but you might experience list view performance degradation as the number of field types in a list increases. List view
Column 2,000 per document library4,096 per list This is not a hard limit, but you might experience library and list view performance degradation as the number of columns in a document library or list increases. Library and list view
Web Part 50 per page This figure is an estimate based on simple Web Parts. The complexity of the Web Parts dictates how many Web Parts can be used on a page before performance is affected. Page

The following table lists the recommended guidelines for people objects.

People object

Guidelines for acceptable performance Notes
Users in groups 2 million per Web site You can add millions of people to your Web site by using Microsoft Windows security groups to manage security instead of using individual users.
User profile 5 million per farm This number represents the number of profiles which can be imported from a directory service, such as Active Directory, into the people profile store.
Security principal 2,000 per Web site The size of the access control list is limited to a few thousand security principals (users and groups in the Web site).

The following table lists the recommended guidelines for search objects.

Search object

Guidelines for acceptable performance Notes
Search indexes One per SSPMaximum 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* This is a hard limit enforced by the system.
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.
Crawl logs 50,000,000 Number of individual log entries in the crawl log.

The following table lists the recommended guidelines for logical architecture objects.

Logical architecture object

Guidelines for acceptable performance Notes
Shared Services Provider (SSP) 3 per farm (20 per farm maximum)  
Zone 5* per farm The number of zones defined for a farm is hard coded to 5.
Web application 99 per SSP This limit includes the number of Web applications on child farms consuming resources on this SSP.
Internet Information Services (IIS) application pool 8 per Web server Maximum number is determined by hardware capabilities.
Site collection 50,000 per Web application  
Content database 100 per Web application  
Site collection 50,000 per database  

The following table lists the recommended guidelines for physical objects.

Physical object

Guidelines for acceptable performance Notes
Index servers 1 per SSP*  
Application servers running Excel Calculation Services No limit  
Query servers No limit Because 100 content databases are supported for each query server, the number of query servers required per farm is based on the number of content databases in the farm. For example, if there are 500 content databases in your farm, you will need at least 5 query servers.
Web server/database server ratio 8 Web servers per database server The scale out factor is dependent upon the mix of operations.
Web server/domain controller ratio 3 Web servers per domain controller Depending on how much authentication traffic is generated, your environment may support a greater number of Web servers per domain controller.

You can find the full article on technet, with graphs and test environment settings that will help to complete the scenario.

Hope it helps!

Hi Craig,

I heard some roumours on a figure arround <30 but I could get NO CONFIRMATION. I’ll keep trying to verify this info and as soon as I can I will update this post.

Cheers!

Hello,
What’s the Guidelines for acceptable performance on SharePoint and max number of task pulling from MS Project? I need to create a master schedule that has 15,000 tasks/lines. Please advise.

Thanks

Hi Rj,
I currently have no metrics that may help you. I haven’t come across a Sharepoint and Project integration…

From my experience in Sharepoint, it treats everything are lists and 15000 are perfectly supported in a list (althou 2000 is the max. recommended for a view!).

I would recommended you to create a small proof of concept. Just create a project site, make a small app that injects tasks into it until you have, lets say 20K tasks. after that make some tests and monitor the machine resources to infer the response capability, lag in the responses, etc.

Good luck!

hi,

is there a guideline for the number of web applications per spwebservice/spfarm?
you mentioned <30 servers… do you count sql servers extra?

thanks!

A very useful article. Thank you very much. Is there any special place i should look for handling lists containing 100 or more columns?

thanks in advance.

Hi Nimi,

I haven’t come across such an article. I cant give you a couple of hints though:
* use and abuse of CAML queries
* select only the columns you will need
* avoid selecting lookup columns in your queries, unless you really need them
* always define the number of rows (Row Limit)

Here you can find a good tool for CAML building http://www.u2u.be/res/Tools/SharePointCamlQueryBuilder.aspx.

Hope this helps!

Sweet blog! I found it while searching on Yahoo
News. Do you have any tips on how to get listed in
Yahoo News? I’ve been trying for a while but I never seem to get there! Cheers
