We are facing the following issue after migration our database server from SQL Server 2008 to SQL Server 2008 R2. It was observed that any query (even simple things like taking 10000 rows from order table) is taking almost twice the amount of time in WISP Server compared to when DB was in Framing PC.
Below is the system resource/config we have
Old configuration – 4 GB RAM, 2 Processors, Win 7 OS (64 Bit), SQL Server 2008 R2 (32 Bit Version)
New configuration – 8 GB RAM, 4 Processors, Win 2008 R2 OS (64 Bit), SQL Server 2008 R2 (64 Bit Version)
SQL Server Memory is set to Default (Max available) which existing as of today in both. We have tried setting this to fixed (4-6 GB). There were no CPU/Memory utilization issues observed around this time which could have affected the performance.
We have tried different solutions from internet. But nothing seems to improve the performance considerably. Please provide your inputs and recommendations for fixing this issue.
