I'm having random issues of poor performance with a DB of 40 Gb.
It has more than 1200 tables but when I execute a reindex on a table (named MOV_MAG) with over one million or records, the issues are solved for some time, but they return after few weeks.
I don't want to schedule a reindex of that table every day, I would like to find where is the cause of these issues.
Some infos of the server:
It is a virtual machine Installed on hyper-v server
It is a dedicated SQL server, no other software are running
There are 3 dedicated phisical cores for 3 virtual processors.
There are 8Gb of reserved ram, 2gb for the system and 6gb for SQL Server
There are 2 virtual disks drives
The first drive is 30Gb (20Gb used) dedicated for the system (10gb free) running win2008R2
The second drive is 100Gb for the data (60gb used)
There is one virtual network adapter 1000Mbits/s and the phisical adapter is fiber optic.
The DB Server version is MS SQL 2008.
Usually there are 30 users connected.
The DB was started twelve years ago and this issue is started one year ago and I'm still trying to find a solution without results.
Can someone help me please?
Thank you in advance
