Composite Applications Best Practices

As with other components of WebSphere Portal, the way in which teamspaces are used will influence the performance of the site. Based on our experience and analysis, the following tips can help you achieve better performance with teamspaces:

∙As the measurements above show, the number of teamspaces on the system influences the capacity of the system. However, the key determining factor is not the total number of teamspaces, but rather the number of teamspaces visible to each user. For example, a site with 1,000 teamspaces visible to all users could have a capacity lower than a site with 5,000 teamspaces where the typical user can see no more than 50 of those.

∙One way to exploit the observation above is to not make teamspaces public by default. Public teamspaces are visible to all users, so a large number of public teamspaces will increase the average number of teamspaces visible to each user.
