What to do with extra RAM
I replaced my Vultr server with 1GB RAM with a Virtono "Black Friday" special with 8GB RAM. I was pushing the 1GB into swap a lot, but it still performed decently.
Now with 8GB RAM, it doesn't need to swap, but I'm only using about 2GB of it. Even after increasing the php-fpm processes and the mariadb innodb_buffer_pool_size.
Any ideas what else I can do to make use of some extra RAM?

Nest virtualize about 200-300 OpenVZ vm's and sell it on LET for $5/year
Use redis or memcached and start filling the memory with cache...
Upload it, so that others that need more ram can download it
Could even monetize it through ads
upload your ram so i can download it.
just downsize it next year.
The new server is about €50/year vs $6/month for the old 1GB Vultr, so pro-rated, it's cheaper.
Donate the unused RAM so that people can download it if needed.
Boot your app into RAM.
One more choice ramdisk......
recode any application you use to run in the Java library instead. Be begging for 80gb of ram soon.
Seriously though run an I2P node which uses 1.5-2gb of ram but only uses around 56 kb/s network and you can explore I2P at your own pace since it takes several hours to a few days to fully boot up each time.
This is the best idea, so far. I'll look into it, thanks.
That's probably the best option.
If downsizing wouldn't make sense in your scenario, you don't need to do anything: the kernel will use this extra ram as a cache.
A tool to download more RAM (yes, seriously!)
You don't need to do anything. The OS will start using it as a disk cache to speed up the system overall. Take a look at my 128GB dedi, where about 41GB is actually allocated to VMs:
See, how even though I have 85GB of "spare" RAM, the system has still chosen to use 16GB of swap for stuff that's never used, and has used 86GB of RAM to cache disk instead, because that data is used more frequently.
You can always set the kernel command line parameter
mem=1Gto limit the usable system memory to 1GiB. It will look like you are still on Vultr. Let not the additional memory act as a distraction coming int the way of optimizing for low memory situations..Put a big file in the
/run/shmfolder to fill up the RAM.After one month, you'll be able to determine whether the provider is selling SWAP as RAM.
