Fast server but slow
Posted on 2014-10-20
I have seen new customer who has Dell T610 server. This is the spec:
PowerEdge T610 Tower Chassis for Up to 8x 3.5" HDDs and Intel
Intel Xeon E5620 Processor (2.40GHz, 4C, 12M Cache, 5.86 GT/s QPI, 80W
TDP, Turbo, HT), DDR3-1066MHz
32GB Memory for 1CPU (4x4GB Dual Rank RDIMMs) 1333MHz
5 x 300GB SAS 6Gbps 15k 3.5" HD Hot Plug
PERC 6/i RAID Controller Card 256MB PCIe, 2x4 Connectors
16X DVD-ROM Drive with SATA Cable
PV HH LTO3-080 400GB Internal Tape Drive with H200A Controller and Cable

It has installed Symantec Backup Exec 2010 R2 and Symantec Endpoint Protection. The server is domain controller - we have 8 pcs onsite and another 7 connecting over vpn. There are Active Directory, DNS, DHCP, Exchange Server 2010, SharePoint 2010 and Terminal Server installed. We have 10 concurrent users using HP Thin Clients connecting to the terminal server all the time. We also have Sage ACT 13 Premium installed on the server which uses SQL. Users mostly use Office programs and Outlook connected to this Exchange (not cached mode). They aslo open PDF files, browse the internet. All of them use Sage ACT 13 Premium. Both Office have fibre optic connection 80/20 mb.
Users complain all the time about the performance of terminal server sessions (rdp). They say that it takes ages to open pdf document sometimes. Other times they wait up to 15 minutes to open Sage Act in their rdp session.
I think that there is just too much on the server. I said that even getting new server will not solve it as the new spec of another £5k Dell T620 server is pretty similar: same SAS 15k drives for example.
Could you advise how to make it all work much faster and better. They have tried Sage ACT 13 access in web browser but it was even worse. There is plenty of space on the hard drives.
Any ideas for improvement?
