Environment:Jenkins v 1.551 on JRE 1.7.51 64 bit on Windows Server 2008 R2 64bit.
All Plugins are all latest versions.
That is: Build-Node-Column Plugin v 0.1
And just in case it is related:
Sectioned View Plugin v 1.18
DropDownViewsTabbar v 1.6
With increasing number of slaves the performance of the build node column display seems to decrease significantly.
In our setup, after increasing number of Slave from 7 to 18, all views that are showing the "Last Build Node" column took more than double time to show.
For example a view containing approximately 70 jobs took about 15 seconds to show with 7 slaves and 55 seconds with 18 slaves.
Monitoring the CPU load (Prcoess Explorer and Jenkins Melody Monitor Plugin) shows a fully loaded CPU-core for the request.
After completely removing the "Last Build Node" column, the same view appears in less than a second.
The number of jobs obviously also has an impact (i.e. a view with 20 jobs and "Last Build Node" column shows in about 5 seconds). But the impact of the number of Slaves seems to be much higher.
I didn't test if the number of Offline versuse Online slaves has an impact.
