Subj:   Re: Performance gain when adding nodes
 
From:   OHara, Daniel

Hi Gebhard,

If the nodes are of the same type and they have the same disk configuration you will get linear scalability. If how ever they are not your Terdata representative has a tool to calculate relative performance based on a standard benchmark. There figures are expressed as T- Perf numbers. This gives a good indication of throughput changes but there may be variations for individual jobs who I/O CPU balance varies from the benchmark.
