Server response slow

Info: The server configuration is as follows

Test server 1:

Server chassis: CHENBRO CHASIS Model: RM-41416B

Motherboard: Intel Server board S2600CP4

Processor: Intel XEON E5-2630 V2 (Single CPU)

RAM: 8GB RAM Samsung ECC RDIMM (2 no’s)

RAID controller: LSI MegaRAID 9271-4i SGL SATA+SAS Part No: LSI00328

RAID level: RAID1 and RAID0

RAID card to HDD connector: Mini SAS to 4 SATA CABLE SAS PCI D33289-003 BIZLINK (Intel)

HDD type: SATA (Seagate Constellation ES.3)

Network: 1 Gbps (2 no’s with route add enabled)

Antivirus and firewall: Symantec Endpoint Protection 12.4 (Firewall disabled)

RAID configuration details: Totally 7 HDDs are connected to the server (All are 1TB SATA HDDs). We have configured 3 RAID1 pairs using 6 HDDS (Each RAID1 is equal to 1TB) and 1 HDD as RAID0.

First RAID1 has 4 partitions. One is for OS and other 3 are used for just keeping very less accessed/ less important waste files).

Other 2 RAID1 HDDs have 4 partitions in each and all are shared over LAN. RAID0 HDD has 8 partitions with low level data and it is also shared over LAN.

Test server 2:

IBM System X3630 M4 Rack Server

Processor:Intel Xeon E5-2420 (6 core, 15MB)

RAM: 8GB

HDD: 4x 1TB (RAID 1)

RAID controller card: M5110 RAID

Problem Description:

Initially the test server 2 was my main server and everything was fine, I changed my main server with test server 1 now the problem started like I faced the problem like the clients experienced the interaction with the server is slow and unable to work fast. So I reverted back the changes in order to do the testing and I made the test server 1 as client but now also I faced some issues with working speed of the server. So I decided to do some loop testing which is...

Test suite1:

For i = 0 To TextBox1.Text

For j = 0 To TextBox2.Text

        If j = TextBox2.Text Then

               Me.Text = j

            End If

      Next

Next

Result:

Loops   Test server 1   Test server 2

         (in sec)      (in sec)

10000   304.0282       301.2274

10000   259.9276       285.3041

10000   234.016        282.9914

20000   985.8125       1247.3977

20000   944.6284       1142.5796

20000   1033.9074      1245.3892

Test suite 2:

1. VB.net

For i = 0 To TextBox1.Text

    If i <> TextBox1.Text Then

         Me.Text = i

    End If

    For j = 0 To TextBox2.Text

    Next

Next

Result:

1. VB.net

Loops   Test server 1   Test server 2

         (in sec)        (in sec)

10000     0.9984         0.6566

10000     0.9984         0.6564

10000     0.9984         0.6406

20000     1.8096         1.4219

20000     2.106           1.4377

20000     2.1216         1.4844

Changes done:

1. 1. I checked the same with the multiple OS like windows 2008 and 2012 but still the same problem repeated
2. 2. Checked without RAID
3. 3. Done complete hardware check with the intel
4. 4. I also tried by removing the RAID and other extra HDDs. I just ran the server with single HDD (That is OS HDD) and still the problem remained same

The test server 2 was lesser capacity server as per hardware configuration. Still the speed of the test server 1 seems slow when it runs the programme.

Is there anything I left to check and is there any other way to solve this problem?? Please help me...

Thank you in advance..
