Description

Optimizes burst test performance when using many EOAs by addressing key bottlenecks:

  • Configurable EOA count: Added NAT_INTEROP_LOADTEST_EOAS environment variable (default: 300)
  • New optimized test: TestBurstOptimized() uses 1/4 fewer EOAs with 4x larger budgets per EOA
  • Improved overdraft handling: Test terminates only when >50% of EOAs fail, not on first failure
  • Optional load balancer: OptimizedRoundRobin with weighted selection to reduce contention

Tests

  • Added TestBurstOptimized() - new optimized version of existing TestBurst()
  • Added setupOptimizedLoadTest() - optimized setup function with fewer EOAs
  • Added getNumEOAs() - helper for configurable EOA count
