: How to calculate maximum number of request in 128 MB VPS performance? I am a newbie here, please let me know if I'm using wrong webmaster terms. I am currently setting up a VPS for a multi

@Sims2060225

No point in "calculating" when you can just test it, as ionFish suggests—especially as the number of concurrent requests a server can handle depends on the application being hosted (as well as the web server, DB server and their configurations). The same VPS can server 6000 requests per second with static pages or just 1 request per second if it's a very processor/memory-intensive page.

In addition to loadimpact, you can also use load/stress testing and webserver benchmarking tools like:


mysqlslap
jmeter
deluge
grinder
httperf
ab
siege
valgrind
fetch
autobench


BTW, all of the above are open source, and more are listed on this page.

I wouldn't worry so much about RAM when it comes to a VPS, you need to think more CPU. A VPS with that little RAM likely has almost no CPU. You'd be better off just getting a reseller/shared account (unless your activity prohibits a shared environment). Users are going to be experiencing severe loading issues with that little amount of resources available.

You could use a stress-tester like this one: loadimpact.com/ which has a free option, but limits it to 50 users. Paid-for (or registered users) can get increased stress levels.

I like this service specifically because it generates very useful graphs, and a detailed report containing page load errors, etc.

There are many other services like this one, each with pros and cons.
