Description

Viper has become quite slow to launch. It takes several seconds to launch even a completely empty installation. We should figure out why and how to optimize this.

Research direction
The issue mentions slow launch time for even empty installations. To investigate, profile the Viper startup using Python's cProfile or similar tools. Focus on the main entry point (likely in viper/ init .py or bin/viper). Check for heavy imports, module loading, or configuration parsing that could be optimized. Since there are no comments or linked PRs, start by reproducing the slowness and then identify bottlenecks.
