Re: [ldm-users] LDM with queue in memory only, without a file on disk

I've got two ingest servers that don't do any processing at all. Didn't know which method was "better", so we did one by setting up a ramdisk in Grub and the other using tmpfs. Both are 8GB (16 on the systems) and run just fine. 

Might bump them to 12GB just for fun.

Ditto here.  Been using ram disks in multiple instances locally without
any issues.

We've put the ldm queue on a diskless partition, and it runs fine. Been
doing this for 5+ years.

I was wondering if it is possible to have a diskless queue for LDM.

Our Primary servers only relay data and in theory the actions do not

need to have I/O access to disk.  If we could avoid the disk I/O it
would speed things up for us.
