Cursor Performance in New Server
Im sorry so long not update this question. I solved this case 2 months after this question.

After few times trial and errors, my biggest impact in performance is using separated harddisk between Operation System and Data.

I try to bought new harddisk and look like changing storage system from RAID to AHCI give quite difference in performance for data processing. Well, we do 1 hour backup in Maintenance Job for safety to online cloud service.

I do some changes in BIOS settings which also gives many impacts to performance descried in this pdf http://h20195.www2.hp.com/v2/GetPDF.aspx%2F4AA3-6555ENW.pdf

Im also upgrading memory to 4x8GB 

Comparing to my old server its 8 times faster now.

Thank you for helps.
