Linux 2.6.38 Boosts Performance

| Thursday, March 17, 2011
The second major Linux kernel release of 2011 is now available, offering open source users enhanced performance over its predecessors.

The Linux 2.6.38 kernel goes a step beyond what Linux developers provided in the 2.6.37 kernel released earlier this year, by eliminating the last main global lock, which further unlocks Linux performance.

"There are many performance enhancements that went into 2.6.38, Transparent Hugepages is one of those noticeable features," Tim Burke, vice president of Linux Engineering at Red Hat told InternetNews.com. "To give you a better idea of how important Red Hat considers transparent hugepages, Red Hat led the initial upstream implementation in the timeframe to include in Red Hat Enterprise Linux 6. We continue to evolve the types of memory use cases to be fully covered by transparent hugepages."

With Transparent Huge Pages (THP), memory allocations for processor use grow from 4 KB in size to 2 MB. Burke explained that THP reduces the number of memory allocations and leverages higher performance hardware.
"The impact of the inclusion of the Transparent Huge Pages (THP) in 2.6.38 is that it will offer improved performance on workloads that requires large amount of memory, such as JVM and database servers," Burke said.

Burke noted that one of the main beneficiaries of THP is virtualization.
