We have a 7.4 meg intel file we are looking to push; however, out of 400 gigs of ram, we are using 400 gigs, with a load average well over 10.... This is only a 3.5 Gb/s sustained link. We have about 2000 lines of intel (cert hash, file hash, domain) currently. This new addition would drive this up to ~35,000 lines of intel. We are trying to determine if this is practical given our current load on the box.

What process is using memory?  Workers? Proxies? Manager?  If you can include the output of 'broctl top' that would be helpful.
