Numbers Don't Lie: 10,000+ Online Without a Hitch
Yesterday I told you why we switched to Bun + Elysia. Today let's talk numbers. When we propose a solution for a language school, the first question from the owner is: "What happens if tomorrow I have 10x more students? Will the system crash?"
With traditional stacks (PHP, Django) the answer was often: "You'll need to upgrade to a more expensive server." With our new stack, the answer is: "Your current server won't even notice the load."
Comparison: Old Guard vs. New Gen
Here's how our current stack compares to what's usually offered on the market (PHP/Laravel or Python/Django):
| Metric | Traditional Stack (PHP/Django) | Our Stack (Elysia + Bun + Redis) |
|---|---|---|
| RAM per 100 users | ~500 MB – 1 GB | ~50 – 100 MB |
| Latency | 100–300 ms | < 10 ms |
| RPS ceiling | 500 – 2,000 req/sec | 50,000 – 100,000+ req/sec |
| Real-time (Chat/Notifications) | Requires workarounds (Pusher/Centrifugo) | Built-in (Native WebSockets) |
What Does "10,000 Online" Really Mean?
For most local IT solutions, 1,000 concurrent users is already something to be proud of. At BridgeCore SYSTEMS, we design architectures that can handle 10,000+ active sessions on ordinary office hardware (e.g. i5 11th Gen).
To put that in perspective:
- 10,000 online is the scale of a major city portal or a federal testing system.
- With our stack, even if every student in the school logs in at 9:00 AM to take a test, the delay is measured in fractions of a second.
Why This Matters for Language Schools
- No lag during tests: Exams are stressful enough. The last thing a student needs is a loading spinner.
- Instant feedback: In language learning, speed matters. Our stack enables interactive exercises where answers are checked faster than you can blink.
- Infrastructure savings: Where competitors need 5 cloud servers, we need one local VPS. That’s especially important in local networks (e.g. Turkmenistan), where every byte of traffic counts.
Our Secret Ingredients
- Redis: All hot data (sessions, active lessons) stays in memory.
- Elysia.js + Static Analysis: The framework understands your routes before the request even arrives, making it one of the fastest in the JS/TS ecosystem.
- Drizzle ORM: Minimal magic, maximum SQL performance.
Conclusion
We don't just write code. We build SYSTEMS that scale with your business. While others spend budget on bigger servers, we spend time on optimization so your software simply works. Fast. Always.
