I am seeing unhealthy snapmirror times; transfer rates on the order of 2MB/s over 10GbE.

 

last-transfer-size     last-transfer-duration

      631.6GB            86:35:23              

      11.16GB            2:12:48               

      755.5GB            91:32:48            

 

Schedule is to run every 10 minutes.

 

The network is clean.  ifstat has not recorded an error in months. 

No duplex mismatches and negotiated speed is 10000.

Network is not maxed out, hits 80% at times.

Jumbo frames are enabled throughout. 

CPU load is low on a pair of FAS6220's.

Systems using the storage get good performance.

Throttle is unlimited.

 

What else do I check?
