Threading Library Improvements
|
Underlying threading routines have been rewritten for higher performance and stability without changes to programming and binary interfaces.
|
Significantly improves scalability and performance of multi-threaded
applications including Java platform based applications. No need to
recompile or rewrite the application to take advantage of performance
enhancements.
|
|
Upgrade release offers new 64-bit support, enhanced security (GSS-API, Authentication and Authorization, Secure Socket Extension), improved logging and assert mechanisms, and IPv6 support.
|
Improved performance for EJBs (Enterprise Java Beans), Java Servlet, and instant messaging. Enhanced security with additional APIs for use by developers.
|
UFS Concurrent Direct I/O
|
UFS direct I/O, which streamlines database access to data devices, was introduced in the Solaris 2.6 platform. The concurrent feature allows multiple cooperating processes, such as those found within database systems, to write to the same file.
|
Improves database performance by approximately 87% over direct I/O alone. Combines the performance of "raw disk" access with the administrative convenience of file systems for database usage. ++
|
Advanced Page Coloring
|
Enhancements have been made to the algorithm that controls virtual/physical pages and how they are cached.
|
These enhancements deliver increased system performance of around 10% for general user loads in servers. The most benefit is realized for machines under heavy loads. ++
|
Enhanced Directory Name Look-up Cache (DNLC)
|
DNLC now provides improved performance when accessing large numbers of files.
|
Dramatically reduces the time required to look up a name in a directory that contains a large number of entries. For example in a recent test, creation of 262,000 files in a single directory was reduced the time from 19 hours to 16 minutes.++
|
mkfs Performance
|
The mkfs command has been updated to improve performance when you create file systems.
|
Reduces the length of time, often from hours to minutes, taken to create UFS file systems with large numbers of files. ++
|
|
Through the in-kernel cache, NCA uses system memory to significantly increase performance for HTTP requests normally handled by web servers. This increases web server performance by reducing the overhead between the kernel and the web server.
|
Significant performance enhancements for both cache-hits and cache-misses. This is accomplished without recoding or recompiling applications.
|
|
IPv6 is the next-generation protocol that is designed to replace the current protocol, IPv4. IPv6 is superior to IPv4 because of the higher number of IP addresses available and improvements to routing and network auto-configuration.
|
Allows developers and end-users to prepare to utilize the next generation of internet technologies.
