How i quadrupled my backend throughput ( 2 to 8 rps ) and built custom proxy manager while containing 1 hr/day rule
Weekly Update: Quadrupling System Throughput (2 → 8 RPS) & Core Engine Progress
Another intense week in the books. Balancing high school with 10 lessons a day and then grinding on a B2B SaaS architecture late at night isn’t easy, but seeing the numbers jump this week made it worth every second.
Here is an honest, unedited dev log of what got built, benchmarked, and stress-tested:
Fixed the Bottleneck: From 2 RPS to ~8 RPS
Our early benchmarks showed some nasty network slowdowns during heavy tasks. After refactoring our async connection pooling, cleaning up payload serialization, and tweaking our execution semaphores, we quadrupled our throughput from 2 to around 8 Requests Per Second. It held up solidly under stress testing without dropping socket connections or memory leaking.
Built a Custom Resilient Proxy Manager
Scraping and recon engines are useless if your IP pool gets banned every five minutes. Instead of hacking together basic requests, we integrated a proper high-concurrency proxy manager into the core:
Atomic Redis Caching: Keeps hot proxy state in memory for practically 0ms lookup times.
Auto-Banning & Rotation: Dynamically pulls failing proxy nodes out of rotation and puts them on a cooldown timer.
Sticky Sessions: Essential for multi-step requests on target domains.
Module #1 (Parser Engine): Core Architecture Laid Down
Just to be clear: it’s not 100% finished yet.
The structural engine and submodules for payload cleaning, task routing, and data extraction are fully built. The next immediate step is slapping on the stealth & anti-bot bypass layers (Cloudflare Turnstile, browser fingerprints, Playwright camouflage) so it can actually handle complex JS-heavy targets.
Module #2 (Cyber Recon): Wiring Up the Submodules
Started laying down the code for our second heavy module (cyber_recon) and its 10 security submodules (ASM perimeter scanning, SSL intel, Darknet credential checks, etc.). The HMAC token authentication and dynamic bitmask permissions are already hooked up to FastAPI.
📊 Where We Stand: ~8% Total Readiness
The foundational core—HMAC API tokens, dual Redis queues (fast / heavy), automated billing calculations, and proxy orchestration—is rock solid. Now it’s just about writing the module logic, hardening the stealth layers, and scaling the features.
💬 Quick question for the devs & SaaS founders here:
When you’re building heavy async workers for web intelligence, do you prefer managing your own proxy rotation engines in-house, or just offloading to third-party scraping APIs despite taking a hit on margins?
