Use excess RAM as cache for Samba?
I have a older workstation with 32gb of RAM that I've repurposed as a server running Ubuntu Server 18.04. Since 32gb is way more than necessary given the limited use (mainly just file sharing and backups), I'm wondering if it's possible to use the remaining RAM as some sort of cache for Samba file sharing (similar to bcache but using RAM instead of SSD). Ramdisk isn't quite what I'm after since I would like the contents in the cache to change based on what is being accessed more frequently.
Is this possible? And if so, could anyone point me towards some resources on how to do it? (Googling thus far has brought me nothing unfortunately)
Thank you!

The requirements for Ubuntu 18.04 minimum advisable for the Desktop version is 2GB. I ran a Samba on an Ubuntu 18.04 with that memory (server version) and I have 12-15 users working continuously. You can quietly use only 2-4 GB. 8 GB, it's already a lot to my understanding

Yes, but the question was how to benefit from the other 30 GB of free RAM the OP has in his machine.

Is there a similar parameter for caching reads instead of writes?

The notes I have are extensive to share here. I have taken it by analyzing the Samba code from the source code. I have never had to compile the code. As it comes in Ubuntu 18.04, with 4GB of RAM, it is enough for me to have 20 users, 10 hours a day, writing and reading documents, videos, backup, and even applications. Everything depends on what you want it for. In addition to the server, the network connection and the type of OS are determining factors. Those 20 users are in a 10G network and they are Windows 10.
