in default socket path does it use virtual memory? about thumbfast HOT 6 CLOSED

On linux it uses /tmp/ for it's files, which usually is usually in RAM.

If you want to make sure, check your /etc/fstab and look for the line that mounts /tmp. If it uses tmpfs, your SSD will be fine 😉.

Here is what that line looks like in my fstab:

tmpfs                                     /tmp            tmpfs   defaults,noatime,mode=1777,size=7G 0 0

But you can also customize it with the socket and thumbnail options, if you would rather have them somewhere else.

I'd say something this would make sense

socket=/dev/shm/thumbfast
thumbnail=/dev/shm/thumbfast.out

Those are the filenames that thumbfast uses by default for the /tmp/ directory.

I checked /etc/fstab it doesn't have tmpfs entry.

Even if it's not in fstab, systemd has a service that sets up tmpfs, so /tmp is probably still using tmpfs.
You should check with mount | grep tmp

@christoph-heinrich Thank you for responding and the info. I checked /etc/fstab it doesn't have tmpfs entry. I decided to use /dev/shm/tmp directory for socket. I'm confused about thumbnail file path. What should I use for it regarding /dev/shm/tmp path?

Thank you for your help. It works well. I hope you document it for other users.
All the best.
