Product Overview

Measure network overhead for main statusgo usage scenarios. Identify and fix the bottlenecks.

Product Description

Main use cases to track:

1. node was started in background(sync was ended) 1.1) node was started in background(sync was ended) + whisper
2. node was started in background(sync is running)
3. node was started in background(upstream) 2.1) node was started in background(upstream) + whisper
4. one chat 1-1. sending messages(60rpm)
5. 60 chats 1-1. receiving messages(10rpm per chat)
6. 10 group chats(60 rpm per chat)
7. 100 chats 1-1. 30 group chats. receiving historic messages for last day(100 messages per chat)

Iterations

Research to define further steps and related metrics. Iteration 1.

Goal Date: 2018-02-13 Description:

• Define reasonable steps to reduce network overhead
• We have tools to measure CPU usage and network of statusgo for main use cases to track progress(part of https://github.com/status-im/ideas/issues/22)(status-go tasks TBD)
• Success metrics for the issue was defined

Minimum Viable Product. Iteration 2.

Goal Date: 2018-02-26

• Reduce Status mean traffic to 50-100Mb/day (2-4 Mb/hour) from current 10-20Gb/day. This relates only to online chatting without offline mailboxing
• Make WhisperV6 production ready and switch to it https://github.com/status-im/status-go/issues/634

Acceptable traffic consumption. Iteration 3.

Goal Date: 2018-03-05

• Reduce Status mean traffic to 10-40Mb/day(0.5-2 Mb/hour)
• Many topics problem resolved https://github.com/status-im/status-react/issues/2964
• Many topics used for topics subscription
• Setup maximum Whesper's peers

Acceptable traffic consumption at the start of Status. Iteration 4.

Goal Date: 2018-03-26

• Reduce traffic overhead on a Status start
• Many topics used for offline mailboxing
• Offline mailboxing sends only messages by given period of time (from-to timestamps)
• Update mail server to send only messages that used doesn't receive yet https://github.com/status-im/status-go/issues/690

Minimal offline mailboxing overhead. Iteration 5.

Goal Date: 2018-04-09

• Further traffic overhead decrease on a Status start
• Use new offline mailboxing API on Clojure script side.

Success Metrics

5 Mb/day of traffic
