Node list performance
As of opCharts version 3.2.6 Node list performance has been improved significantly and will be noticeable on systems with higher node counts, particularly on the node list page and on and scheduled outage page.
There are two basic modes that can be run: db off and db on. db off has cache running in memory. db on uses the db for caching. When db is set to on the nodesum files are cached into the db and filters are run against the db instead of doing the filters manually in memory. NMISx db caching is now the faster option. By default this config item is turned off, to enable this edit your opCommon.nmis file located at /usr/local/omk/conf/opCommon.nmis and set nmisx_db_cache_enable to 1.
