Solana Compute Budget: How to Right-Size CU Limits in Bot Txns

Setting compute unit limits too high wastes priority fee spend while setting them too low causes silent transaction failures mid-execution — and most bot developers never simulate CU consumption before going live. This post shows how to use simulateTransaction to profile actual consumption, automate limit padding by instruction type, and monitor compute efficiency across a fleet.
