> Currently on the first page load (if there is no limit set) the whole jobs execution
history is loaded since the begging of the time. On large amount of rows returned (10k+) page
load time grows dramatically, causing 1min+ delay in Chrome and freezing the process in Firefox,
Safari and IE.
> A simple inspection in Chrome shows that network is not an issue here and only causes
a small latency (<1s) while most of the time is spend in UI  processing the results even
according to chrome devtools:
