Tocalculatethemaximum connection time for clients, use this formula:

(MaxCore DIV NumProcs) x Rollover

Example: (4 DIV 2) X 3600 = 7200 seconds (2 hours)

Tocalculatethetotalnumberofprocesses,usethisformula:

Number of Scopes X NumProcs X MaxCores

Exampleusing<Distribute>adaptor</Distribute> with two adaptors:

2 X 2 X 4 = 16 Core processes

TocalculatetheamountofRAMrequiredtosupportthedistributedprocesses,multiplythetotal

Close idle connections

New feature in Flash Media Streaming Server and Flash Media Interactive Server; requires Flash

Player 6 or later.

When clients leave an application, their connection is oen le open. Flash Media Server 3 can

now detect these idle connections and reclaim their resources for new and active clients. When a

clienthasbeenidlelongerthanthemaximumspeciedidletime,(thedefaultis10minutes),the

serverwillclosetheconnection.Toenablethisfeature,youmustsetAutoCloseIdle-

Clients to true in the Server.xml le.OnceitisenabledintheServer.xml le, you can

disable it for individual virtual hosts or individual applications in the Vhost.xml and

Application.x ml les.

Limit connection requests

New feature in Flash Media Streaming Server and Flash Media Interactive Server; requires Flash

Player 6 or later.

Insomecases,ifmanyclientsareattemptingtoconnecttotheserver,thequalityofservicecan

be diminished for those clients who are already connected. By setting the MaxConnection

Rate in the Server.xml le, you can limit the number of connection requests per second that

are accepted.
