Before consider the ideas to improve the performance mind what the SMP Implementation Guide says:

  • Symantec does not recommend that you install SQL Server on a virtual
  • When Notification Server is installed on a virtual computer, the data loader
    show performance degradation (approximately 25%).

Some ideas to improve the SMP performance

  • Improving IIS and Notification Server response times by disabling debug mode using disableweb.exe. Article URL Download the, extract, and execute disablewebdebug.exe /fix.
  • Defrag regularly the drives of your SMP Server and SQL Server to have a better I/O.
  • Creating a maintenance plan in SQL Server 2005 or 2008 to optimize database performance: Article URL
  • On the SQL Server set Windows’ memory usage to favor Programs over System Cache. SQL Server does its own data caching to improve performance, and the more memory reserved for its use, the more efficient its caching can be. Article URL with a lot of SQL server performance recomendations.
  • Agent configuration schedule to 03 or 04 hours.

New Protogon File System In Windows 8 Developer Preview


Protogon is the name of the new file system that is found in initial and leaked version of the Windows 8 Beta (Windows Developer Preview). References to the Protogon file system is found in the leaked versions 7955 and 7959 (It may be there in other version, but I came across Protogon references to these two versions).

The drive or partition that is formatted using Protogon is not readable using Windows 7 and earlier versions as well as any other operating systems such as Mac Osx Leopard/Lion. It is also quite uncertain that whether the stable release or upcoming beta release of windows 8 will be able to read the Protogon partitions or not.

Protogon differs from FAT32 and NTFS obvious way, is the minimum volume size requirements. Windows will refuse to format the drive with Protogon if the size is less than 512 MB. says that Protogon seems to include or incorporate the database like concepts such as transactions, rows, tables, cursors, etc. Protogon could replace or emulate the NTFS.


1. Open command prompt with Administrator privileges
2. Enter the command. format DriveLetter: /FS:protogon /Q and hit enter.

/Q designates the quick format.

Once format process is complete, windows throws the warning message that “Please be advised that the underlying format may be incompatible with near-future versions.”

Testers of Protogon file system have reported that Protogon is not only fast as compared to NTFS but, also provides more usable disk space than NTFS.

What Is Root Hints?

If the DNS server does not know the address of the requested site, then it will forward the request to another DNS server. In order to do so, the DNS server must know of the IP address of another DNS server that it can forward the request to. This is the job of root hints. Root hints provides a list of IP addresses of DNS servers that are considered to be authoritative at the root level of the DNS hierarchy(also known as root name server).

The good news is that root hints are preconfigured on Windows Server 2003 DNS servers. The root hints are stored in a file named cache.dns that is located in the WindowsSystem32Dns folder. If you would like to see what the root hints file looks like, you can open it in Notepad. The root hints file is really nothing more than just a text file that pairs root DNS servers with their IP addresses.
