Server Optimisation for huge customers

[youstable]

Hi,

We are running a Free Web Hosting platform that has good numbers of after we switched to DirectAdmin server load is very high and it goes offline multiple times in a day, we have done these things to keep services up and running

1. Installed OpenLiteSpeed
2. Disabled all Crons Features
3. Using Php Php 7.1 and 7.3
4. CloudLinux installed on the server

It has XXXXX numbers of accounts and XXXX active users server specs are Ex: 64GB RAM, Xeon E5 Dual CPU 16 cores, 1GBPS Uplink, 2X2TB SSD. Can you please advise me how to optimise this server with better performance with basic hosting features to our free hosting customers?

Use Opcache/Memcached, check mysql/mariadb optimization. Check iotop/atop what exactly make such load

Does every X hide a real number? So you state you host 10000 < accounts < 99999? And 1000 < active users < 9999 ? If so, you might simply hit IO/wait, CPU, RAM limits, and no software optimization might help you.

Install a monitoring software and see where you have bottle-necks, fix them.

monitoring software

Can you suggest this?

Can you suggest this?

at least use: top, atop, iftop, iotop, iostat, mysqltuner, also check logs

No such thing as free.

server load is very high and it goes offline multiple times

Servers aren't infinite. They are really physically limited pieces of hardware and resources. Unlimited is a marketing ploy. Overselling is not smart.

It has XXXXX numbers of accounts and XXXX active users server specs

What is your real account density? Are you trying to host 10,000 accounts on 1 server?

1GBPS Uplink

Have you calculated your active session size then divided that by 1000?

after we switched to DirectAdmin

You switch from what? Cpanel? Since they were going you charge you all of those 10000.. accounts. Again life isn't free. Find the sweet spot in your servers and keep it there. If its 1000 accounts/per server buy 10 more servers. Still cheaper than Cpanel.

No such thing as free.

maybe they add ads via nginx to hosted websites
such server costs about 100$/mo and they support it and share it for free? hmm..

Like said no such thing as free. If there is a $ or a euro or rupee. Somewhere it isn’t free
