+PraisonAI Agents - Comprehensive Performance Benchmark
+======================================================================
+
+This benchmark measures:
+  1. Agent instantiation time (how fast an agent object is created)
+  2. Memory footprint (how much memory an agent uses)
+
+Methodology:
+  - 10 warmup runs (not measured)
+  - 1000 measured iterations
+  - tracemalloc for memory measurement
+  - Baseline subtraction for accuracy
+
+Frameworks available:
+  - PraisonAI: ✅
+  - Agno: ✅
+  - PydanticAI: ✅
+  - OpenAI Agents SDK: ✅
+  - LangGraph: ✅
+  - CrewAI: ✅
