Linode new SSD Host (2014 May) vs Original Host Compare
Type(Type) 2014/5/11 20:11 (Since 2014/5/11 20:07)

Performance Compare: Linode new SSD Host (2014 May) vs Original Linode (2013)





CPU performance raise about 20%



Old Linode box: Intel(R) Xeon(R) CPU E5-2670 @ 2.60GHz
New Linode box: Intel(R) Xeon(R) CPU E5-2680 v2 @ 2.80GHz

Stream Test: About 20% raise (stream_omp64)

11 / 9 = 220%

Note: No more CPU stealing from your neighberhood with low cost plan. Much more fair.

HDD performance raised about 240%+



2542 / 744 = 340%
