From cf3c66c0eadd268ef525abe16929978581d92f07 Mon Sep 17 00:00:00 2001 From: czlonkowski <56956555+czlonkowski@users.noreply.github.com> Date: Wed, 8 Oct 2025 09:43:33 +0200 Subject: [PATCH] feat: replace placeholder benchmarks with meaningful MCP tool performance tests MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace generic placeholder benchmarks with real-world MCP tool performance benchmarks using production database (525+ nodes). Changes: - Delete sample.bench.ts (generic JS benchmarks not relevant to n8n-mcp) - Add mcp-tools.bench.ts with 8 benchmarks covering 4 critical MCP tools: * search_nodes: FTS5 search performance (common/AI queries) * get_node_essentials: Property filtering performance * list_nodes: Pagination performance (all nodes/AI tools) * validate_node_operation: Configuration validation performance - Clarify database-queries.bench.ts uses mock data, not production data - Update benchmark index to export new suite These benchmarks measure what AI assistants actually experience when calling MCP tools, making them the most meaningful performance metric for the system. Target performance: <20ms for search, <10ms for essentials, <15ms for validation. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- tests/benchmarks/database-queries.bench.ts | 11 ++ tests/benchmarks/index.ts | 6 +- tests/benchmarks/mcp-tools.bench.ts | 169 +++++++++++++++++++++ tests/benchmarks/sample.bench.ts | 47 ------ 4 files changed, 181 insertions(+), 52 deletions(-) create mode 100644 tests/benchmarks/mcp-tools.bench.ts delete mode 100644 tests/benchmarks/sample.bench.ts diff --git a/tests/benchmarks/database-queries.bench.ts b/tests/benchmarks/database-queries.bench.ts index 99d20a7..481c403 100644 --- a/tests/benchmarks/database-queries.bench.ts +++ b/tests/benchmarks/database-queries.bench.ts @@ -4,6 +4,17 @@ import { SQLiteStorageService } from '../../src/services/sqlite-storage-service' import { NodeFactory } from '../factories/node-factory';
