We have a couple of new DD6300 configured with around 100TB for backup storage. We are quite new to DataDomains and we are probably doing something wrong with our configuration. The read performance is currently too low to be practical. I'm having difficulty determining what we should be seeing as there doesn't seem to be much documentation on actual performance expectations for each configurable, so i'm asking this forum for help.

At the moment, Configured as a CIFS File share, it has LZ compression enabled, 20% random, 80% sequential and a single 10GBe connection to our network. I have about 16TB of data on the DD, of random types, output from our backup system (Commvault). Normal case, if i copy using Windows Explorer, i will see about 6-12MB/s read speed from the DataDomain share. Best case scenario (i'm not sure the situation that arises that allows this) i'll see 40-50MB/s copying the same files in Windows Explorer from the Data Domain.

I need to configure these devices to achieve around ~100MB/s read performance in normal operation to make restores practical. Any compression is a bonus once we have established an acceptable read speed.

Should i turn off LZ compression? Do i need to install DDBoost somewhere? Is there a way to see what the Data Domain is doing?  I tried system show performance, it shows 11.9 MiB/s with 113 iOPS, 47ms read protocol latency and 4 read streams. Every other column is 0.00. the CPU charts show 0-5% CPU load at all times.
