Overview and Implementation

Some tests permit us to check that some configuration that would help you to improve Windows 2003 file server performance.

Though, these configurations help you, use these changes without testing them

First May end yours network.

Also, this configuration was testing with only one server in the network, and there no Knowledgebase what is the effect of multiple servers in network.

Please backup the system state and the registry of all the operating systems that you intend to modify there configuration, before making change. Also, I dont suggest to apply this modifications on production server.

Windows Server 2003 Tunings

Windows 2003 built 3790 (RTM) that used only for file server in the network:

Created HKLM\System\CurrentControlSet\Control\SessionManag er\MemoryManagement\PagedPoolSize set to 192,000,000.
Windows normally calculates the paged and non paged pool memory sizes using complex algorithms based on physical memory size. These settings allow you to override and manually specify values.
Created HKLM\System\CurrentControlSet\Control\FileSystem\N tfsDisable8dot3NameCreation to 1.

You can increase NTFS performance if you disable 8.3 name creations.
(Some 16bit programs may have trouble finding Long File Names. Don't set this option if you wish to install Norton NT Utilities.)
Created HKLM\System\CurrentControlSet\Control\FileSystem\D isablelastaccess and set to 1.

This will disable the last access information written to each file as it is accessed.

The result is faster hard disk file read-access.

Created HKLM\System\CurrentControlSet\Services\tcpip\Param eters\NumTcbTablePartitions and set to 8.

The value of this entry can be changed to partition the TCP control block (TCB) table to avoid contention. The default is 0x4; the value should be a power of two, that is, 2, 4, 8, 16, 32, and so on. On multiprocessor systems, change the number of partitions to four times the number of processors in your system.
Created HKLM\System\CurrentControlSet\Services\tcpip\Param eters\TcpAckFrequency and set to 13.

Frequency of TCP ACK message that send to the other side.
Client Operating System Tunings

Windows XP with Service Pack 1:

Created

HKLM\System\CurrentControlSet\Services\tcpip\Param eters\TcpAckFrequency and set to 13.

Frequency of TCP ACK message that send to the other side.
Created
HKLM\System\CurrentControlSet\Services\Lanmanworks tation\Parameters\DisableByteRangeLockingOnReadOnl yFiles set to 1.
