# ADLee's ZSH Configuration (Optimized)

# Optimizations:
|
|
# - Deferred/lazy loading for heavy plugins

# - Parallel background loading where possible

# - Compiled zsh files (.zwc) for faster parsing
|
|
# - Minimal command -v checks (cached)

|
# --- Profiling (uncomment to debug slow startup) ---
|

# zmodload zsh/zprof

|
|
# Instant Prompt (show prompt immediately while loading continues)
