dhaupin Efficiency Review
Is this efficient?
The Question
What does it cost to run?
Money. Time. Resources.
What To Check
1. Compute
// What's the cost?
// CPU time per request
// Memory per request
| Resource | High | Fix |
|---|---|---|
| CPU | Loop complex | Optimize |
| Memory | Store all | Stream |
| GPU | N/A | N/A |
2. Network
// How many calls?
callAPI() // 1
callAPI() // 2
| Pattern | Issue | Fix |
|---|---|---|
| Multiple calls | Round trips | Batch |
| Large payloads | Bandwidth | Compress |
| No compression | Raw | gzip |
3. Storage
// What are we storing?
db.save(everything)
// vs
db.save(needed)
| Pattern | Issue | Fix |
|---|---|---|
| Save all | Extra storage | Save needed |
| Keep forever | bloat | TTL/expiry |
| No index | Slow reads | Index |
4. API Calls
# External APIs cost
curl api.com // $$
curl api.com // $$
| Check | Issue | Fix |
|---|---|---|
| No cache | Pay each time | Cache |
| Same call twice | Redundant | Dedup |
| No batching | N calls | Batch |
Cost Estimate
// Estimate: (calls × cost) + (compute × cost) + (storage × cost)
| Item | Calculation |
|---|---|
| API calls | calls × $0.001 |
| Compute | hours × $0.05 |
| Storage | GB × $0.02 |
