Company migrated to new infrastructurea few months ago. Since then performance is slow compared to previous system.Old system was 32bit SQL Server 2005.Physical server,SAN storage.Now it's64-bit SQL Server 2014,Virtual machine,16 Cores,128 GB RAMSAN Storage (Nimble system) is usedMain focus is on SCEKE database performance.What changed compared to old environment - they added High Availability setup.And unfortunatly Secondary server is heavily used...What looks strange is:SCEKE database has 24-28 Filegroups.Mostly one Filegroup has one Data File.Log file is on L:\ driveBut one huge 563 GB data file 'Scene_Data2' also lives in L:\ drive.Probably interfering with Log file.. or it doesn't matter with SAN storage..?On PRIMARY filegroup they have2 TB 'ProvidianClassic1_Data' file and that 563 GB 'Scene_Data2' fileOther data files are 20-30 GB all.Three of them are empty...They have one huge 2TB table "Poink" table.It' son PRIMARY filegroup.I think it's stored in that 2TB 'ProvidianClassic1_Data' data file.Another strange thingwhen I go to Disk Usage Report in SSMSFile Growth events sometimes occur 6 times a per minute.For example on 10/3/2016 Log File Auto Growth ProvidianClassic1_Loghappened 6 times within 5 minutes window...Disk Usage and File Growth stats are attached in Excel below.
