out of the roof IOPS

don't know where to post this but RAM disk from starwind gave me this

This is why there is such an interest around in-memory databases/ analytics/ computing.

ya even NVMe can't beat it....btw this is quad channel ddr3-1866 on e5-1620 V2

is that test done over network ?

Probably not.

Here's the read write bench on my ramdisk:

benchmark on the ram drive:

for certain scenarios, having all the data on a ramdisk is a no brainer!

nope....this isn't done over network.

There is a way to test RAM drive performance over the network too. You can use StarWind Virtual SAN Free for this purposes. It is capable of creating a RAM drive and providing it to the network as iSCSI target allowing you to benchmark network RAM drive performance with any convenient benchmarking tool as an iSCSI attached local storage.
Furthermore, there is an option to create a highly-available RAM-based storage that is mirrored between two or more hosts protecting the data in it from server power outage. We use this feature to store some temporary intensively accessed data and it works like a charm.

Yes, RAM is fast

Also with scst it's pretty easy to share either a ramdisk or nullio-target, good way to see the limits of the network/transport involved...
