Why FERRUM?
You have options. Here's why leading e-commerce companies choose FERRUM for their pricing infrastructure.
The Problem You're Facing
Slow Pricing Calculations
Your cart takes 2-5 seconds to calculate B2B prices. Customers abandon. Revenue lost.
Complex Price Rules
Every pricing change requires a developer. Stored procedures nobody understands. Deployment fear.
Black Friday Nightmares
Your database can't handle the load. Servers crash. Your biggest sales day becomes your biggest disaster.
B2B Pricing Chaos
Customer contracts, group discounts, volume tiers—scattered across systems. Sales reps quote wrong prices.
Head-to-Head Comparisons
FERRUM vs MySQL / PostgreSQL
Traditional databases with stored procedures
| Metric | MySQL / PostgreSQL | FERRUM | Advantage |
|---|---|---|---|
| B2B Price Lookup | 1-5K ops/sec | 3.17M ops/sec | 3,170x faster |
| Query Latency | 50-200ms | 0.165ms | 1,200x faster |
| Memory (10K products) | 50+ MB | 2 MB | 25x smaller |
| Price Rule Evaluation | Stored procedure | Native JSON engine | No code deploys |
Verdict: FERRUM eliminates complex JOINs and stored procedures. Real-time pricing without database load.
FERRUM vs Redis
General-purpose in-memory cache
| Metric | Redis | FERRUM | Advantage |
|---|---|---|---|
| B2B Price Lookup | ~100K ops/sec | 3.17M ops/sec | 32x faster |
| Price Fallback Chain | App-layer logic | Native 7-level | Built-in |
| Volume Tier Pricing | Custom Lua scripts | Native BPRICE.TIER | Zero code |
| Tag Invalidation | Not native | FLUSH NS catalog | Native support |
Verdict: Redis is general-purpose. FERRUM is purpose-built for pricing. Use the right tool.
FERRUM vs Application Layer Caching
In-memory caching in your application
| Metric | Application Layer Caching | FERRUM | Advantage |
|---|---|---|---|
| Rule Evaluation | ~10K/sec | 1.4M/sec | 140x faster |
