User has reported a performance problem on 1.0-rc3 loading the dashboard.

It appears from a brief analysis of their HAR file – attached here – that /blue/pipelines takes 33 seconds to load and search taking 30s or so: 

JENKINSDOMAIN/blue/rest/search/?q=type:pipeline;excludedFromFlattening:jenkins.branch.MultiBranchProject,hudson.matrix.MatrixProject&filter=no-folders&start=0&limit=26. The response is about the normal size expected (perhaps slightly larger, but not large enough to explain the load time, content can be seen in the har file).
