Description

Responsiveness, memory-usage, disk-usage, sync speed. What we want to hit for 1.0

cmollekopf moved this task from Backlog to Later on the Kube: Roadmap board.

cmollekopf renamed this task from Gather non-functional requirements for Kube Mail to Kube Mail non-functional requirements .

No user interaction shall take longer than 100ms at any time (also not under load). Of course asynchronous operations may take longer, but should not block the user in any way.
Memory usage: No process should use 100MB
Disk usage: No more than twice the payload size (e.g. mime message in utf8 * 2). That includes secondary indexes and hopefully fulltext indexing (although that might be too ambitious initially)
A resync check without anything to actually sync on localhost should not take any longer than 5s.

These are of course all made-up numbers that we may want to adjust over time.
