Improve models performance

**Description**
Currently handlers lacks proper timeout support.

**Proposed solution**
Add configurable timeout with sensible defaults.

**Priority**: Low/Medium

Start by locating the handlers mentioned in the issue and checking how model operations currently wait or terminate. Review any existing configuration and timeout handling before deciding where the setting belongs. Done means handlers honor a configurable timeout with sensible defaults, with behavior verified for both configured and default values.
