We have four WG5500s (two Dell and two Intel) clustered together, one of each manufacturer take the majority of the traffic for their site, between 400-700 requests per second. Pre upgrade they had an average load of .5-1.2 with peaks around 3. Since upgrading to the new train I average a load of 5 and peak around 9. I know that neither of these numbers are large enough to concern me on 16 and 24 core boxes, but what accounts for the increased load?
Has anyone else experienced this?
