BE2014 Deduplication - how many concurrent jobs do you run, what spec is your backup server?

Hi

I have a couple of quick questions about the dedupe store concurrent jobs setting (for a standard dedupe store running on the media server, with no external devices and no OSTs).

What do people normally leave the setting at? It's looking like i'm going to be running quite a few jobs at once, but i'm hesitant to perform more than 3 jobs at once as it might slow all the jobs down to much

I have BE running as a VM, with 2 x dual core processors, with 32GB of RAM. If i double this to 8 cores in total, will it help me run more concurrent jobs efficiently?

Thanks in advance for your opinions
