TLI Benchmarks Status

Last Updated: 2025-10-02 (Wave 36, Agent 6)

Overview

All TLI benchmarks have been temporarily disabled due to missing protobuf definitions and type mismatches. These benchmarks are ready to be re-enabled once the underlying infrastructure is in place.

---

Disabled Benchmarks

1. serialization_benchmarks.rs ✅ DISABLED

Status: Fully commented out with placeholder main() Reason: Missing protobuf message definitions

Missing Types:

• Order (standalone message) - proto only has OrderUpdateEvent and order fields in responses
• ListOrdersResponse - not defined in proto
• OrderUpdate - proto has OrderUpdateEvent instead
• MetricValue - proto has Metric instead

Original Test Coverage:

• Protobuf encode/decode performance
• JSON serialization comparison
• Batch serialization operations (1000+ orders)
• Large data structure serialization (100-10,000 items)
• Streaming message overhead
• Memory allocation patterns
• Concurrent serialization (multi-threaded)

To Re-enable:

1. Add missing proto message definitions to tli/proto/trading.proto
2. Rewrite benchmarks to use existing proto types (GetOrderStatusResponse, OrderUpdateEvent, Metric)
3. OR create separate benchmark-specific proto messages
4. Compile proto files with tli/build.rs
5. Uncomment benchmark code and remove placeholder main()

Related Files:

• tli/proto/trading.proto - contains actual protobuf definitions
• tli/build.rs - compiles proto files to Rust code

---

2. client_performance.rs ✅ DISABLED

Status: Fully commented out with placeholder main() Reason: Missing type definitions and exports

Missing Types:

• ServiceEndpoints - not exported from tli crate
• TliClient - not exported from tli crate
• Order, ListOrdersResponse, OrderUpdate - missing proto definitions
• ServiceHealth in tli::client module

Missing Fields:

• ServiceEndpoints: risk_management, ml_signals, health_check
• SubmitOrderRequest: client_order_id, stop_price, time_in_force
• CancelOrderRequest: symbol
• GetConfigRequest: key field
• GetMetricsRequest: start_time_unix_nanos, end_time_unix_nanos

Missing Dependencies:

• http crate for URI parsing

Original Test Coverage:

• Client creation and configuration
• Endpoint parsing and validation
• Connection pooling and management
• gRPC request/response cycles
• Streaming operations
• Concurrent client operations (1-16 threads)
• Error handling scenarios
• Memory usage patterns
• Configuration management
• Health check aggregation

To Re-enable:

1. Add missing exports to tli/src/lib.rs
2. Update ServiceEndpoints structure with missing fields
3. Add missing protobuf definitions
4. Update request structures with required fields
5. Add http crate to dependencies if needed
6. Uncomment benchmark code and remove placeholder main()

---

3. configuration_benchmarks.rs ✅ DISABLED

Status: Fully commented out with placeholder main() Reason: Type mismatch and missing dependencies

Issues:

• Type mismatch: order_side_to_string expects TliOrderSide but receives OrderSide
• Missing futures crate in dev-dependencies
• Inconsistent type naming between modules

Original Test Coverage:

• Timestamp conversion operations (unix_nanos <-> SystemTime)
• Validation operations (symbols, quantities, prices)
• Type conversions (OrderSide, OrderType, OrderStatus, SystemStatus)
• Metric creation with various label counts
• Position calculations (small/medium/large/short positions)
• Concurrent validation (1-16 parallel threads)
• String operations (formatting, case conversion)
• Memory allocation (HashMap, Vec with different capacities)
• Error handling (Result creation, matching, formatting)

To Re-enable:

1. Add futures to tli/Cargo.toml [dev-dependencies]
2. Align TliOrderSide and OrderSide types
3. Ensure consistent type usage across modules
4. Update conversion functions to use correct types
5. Verify all type imports
6. Uncomment benchmark code and remove placeholder main()

Active Benchmarks

None currently active.

All benchmarks have been disabled to eliminate compilation errors during Wave 36.

TODO

High Priority (P1)

1. Add missing protobuf definitions to tli/proto/trading.proto:

   • Order message (or reuse existing types)
   • ListOrdersResponse message
   • OrderUpdate / OrderUpdateEvent alignment
   • MetricValue / Metric alignment

2. Fix type system consistency:

   • Align TliOrderSide and OrderSide types
   • Export required types from tli/src/lib.rs
   • Add missing fields to request/response structures

3. Update dependencies:

   • Add http crate if needed for URI parsing
   • Add futures to dev-dependencies for async benchmarks

Medium Priority (P2)

4. Re-enable serialization_benchmarks.rs:

   • Verify protobuf compilation
   • Test encode/decode performance
   • Validate batch operations

5. Re-enable client_performance.rs:

   • Verify client exports
   • Test connection pooling
   • Validate concurrent operations

6. Re-enable configuration_benchmarks.rs:

   • Verify type conversions
   • Test validation operations
   • Validate concurrent validation

Low Priority (P3)

7. Add new benchmarks:
   • Terminal UI rendering performance
   • Real-time data streaming
   • Command parsing and execution
   • State management updates

Benchmark Architecture Notes

Current Design

• All benchmarks use Criterion.rs framework
• Structured as separate files in tli/benches/
• Each benchmark file is independent with its own criterion_main!()
• Disabled benchmarks include placeholder main() to keep files valid

Performance Targets (from original benchmarks)

• Serialization: Measure protobuf vs JSON overhead
• Client Operations: Track gRPC round-trip latency
• Concurrent Operations: Test scalability from 1-16 threads
• Memory Patterns: Monitor allocation efficiency
• Streaming: Measure throughput for real-time updates

Test Data Sizes

• Small: 10-100 items (typical UI updates)
• Medium: 100-1,000 items (batch operations)
• Large: 1,000-10,000 items (stress testing)

How to Verify Status

# Check if benchmarks compile (should show 0 errors)
cargo bench -p tli --no-run 2>&1 | grep "^error" | wc -l

# List all benchmark files
ls -la tli/benches/

# View detailed benchmark status
cat tli/BENCHMARKS_STATUS.md

# When ready to re-enable, remove placeholder main() and uncomment code
