What can be done with a heavy load on the server?

The situation is this - traffic has increased dramatically, the number of requests to the server has increased and the page loading speed has decreased - the site slows down a lot. It is clear that you need to increase the capacity - move to a more productive server and preferably a separate physical one.
But when you need to solve the problem urgently and very budget, what can be done?

* memcached
* correct nginx setup. Including cache on the user's side not only static, say for 3 seconds.
* remove all unnecessary
* move the database to another server.
* move statics to CDN

1. Install and properly configure the caching plugin
2. Optimize and minify js, if possible, load them from CDN
3. Use https://jetpack.me/support/photon/
for images 4. Refactor the theme code

To begin with, figure out why it slows down (disk, memory, percent, code, locks in the database, extra bots, traffic) and try to eliminate the bottleneck (for example, if there is a lot of free memory and cpu mysql is eating, it makes sense to turn the config towards a more aggressive memory usage). It is possible that one particular page slows down in general and it can be cached for 5-10 minutes into statics by cron. There are many options, but you need to understand what happened.
If there are no hands and a head, then move to cheap ssd virtual machines (if possible, several) with an hourly payment, then move to powerful servers.

of the free ones, the WP Super Cache plugin is good; of the paid ones, take rocket - an order of magnitude better and easier.
if not from the Russian Federation, then CloudFire - 37% compresses traffic for me.
Also, install a profiler plugin, cut off "gluttonous" plugins, i.e. minimize the number of queries to the database.
