Our entire SharePoint Intranet renders at the speed of molasses dripping in winter. When I look at render time for native controls like "zz9_Menu" and "ctl00_SPNavigation", I see render times of 1.7 and 2.46 seconds, respectively. Whole pages can take several minutes to render in the browser. Checking in a file or uploading a file are both painful. I have no large lists that are called in the default view of any list. This is not just one or two sites in the site collection. It's everywhere.
I can find no hardware or software bottlenecks or errors, as determined by Windows task manager, SolarWinds, Event logs, and SharePoint logs. My dba tells me that all is well on the SQL server. I just downloaded Idera's diagnostic manager and am about to dive into the documentation to see what it can tell me.
We have one WFE and one SQL server, AAM to include both the short gfweb and the FQDN version (that last after event log complaints about FQDN requests) of the Intranet URL. These are both physical boxes. Internet and network connectivity to other apps appears to be stellar.
The full crawl is set for Saturdays at 12:00 AM and incrementals at 6AM, 10, 2, and 6PM. I have not reset the index. Performance is only mildly worse when the crawl is taking place, although the last full crawl (of an 80GB content database) took 30 hours and the last incremental took just over an hour, while the current incremental is now at 1:36:00.
Complaints from users abound and I can't put my finger on what is wrong. Any suggestions will be greatly appreciated.
Thanks for your help.
