Description
Running an insert only workload on two identical machines shows an 18% performance hit with SSL enabled over an 11h run, as indicated by the number of bytes written and the number of inserts reported by the client.
There's also a 17% increase in the number of private bytes and a small but consistent 5% increase in user time CPU for the SSL enabled version.
The tests are done on the same physical machine in 2 hyper-V VMs with the client on a third Ubuntu VM, so network is not the bottleneck. All the VMs are also on different physical hard drives.
detailed windows performance counters and some basic analysis are attached in the excel spreadsheet.
