Intel Xeon E7-4807 vs Intel Xeon X5690
Intel Xeon E7-4807 vs Intel Xeon X5690
We replaced our main line of business server with a new one. The old server had dual Xeon X5690s in it (2 generation old chip), the new server has quad Xeon E7-4807s. We expect processor performance to at least stay the same.
Our main java app showed a 50% performance hit and on running a sysbench against the two machines, the old processors were 50% faster.
Is this a particularly bad chip ? Is there something we are missing performance wise ?
(Os on both is Centos 5.10 x86_64 and memory is 128GB)
