             Summary: performance spike on Local channels originated using ARI
                 Key: ASTERISK-22963
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-22963
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Core/Bridging, Resources/res_ari
    Affects Versions: 12.0.0-beta2
            Reporter: Matt Jordan


Using an AMI Originate with an optimizing Local channel:

{noformat}
action: Originate
Application: Dial
Data: Local/201 at queue
Channel: SIP/200
{noformat}

Asterisk consumes about 6% cpu.

With a non-optimizing Local channel, the consumption goes up quite a bit:

{noformat}
action: Originate
Application: Dial
Data: Local/201 at queue/n
Channel: SIP/200
{noformat}

Asterisk now consumes about 17% cpu.  This seems to run with g722 on both ends.  There isn't any transcoding stuff in the output of Action: Status.

With the call bridged via ARI, I see 57% cpu, with the transcoding stuff.

So it may be ARI specific, or I guess it could be something I'm doing wrong when we create the bridge.  My bridge creation is a POST to "http://localhost/ari/bridges?type=".

{noformat}
Action: BridgeList reports:

Event: BridgeListItem
BridgeUniqueid: 6d05c058-7ec4-47d7-a029-08dca733ddfe
BridgeType: basic
BridgeTechnology: simple_bridge
BridgeNumChannels: 2
