Memory Management Improvements
A recent report on the lkml suggested improved IO/writeback performance in the recently released 2.6.24-rc1 kernel compared to the earlier 2.6.19.2 and 2.6.22.6 kernels. Credit was given to some patches by Peter Zijlstra. Ingo Molnar replied, "wow, really nice results! Peter does know how to make stuff fast Now lets pick up some of Peter's other, previously discarded patches as well :-)" He pointed to several patches "as a starter", then quipped, "I think the MM should get out of deep-feature-freeze mode - there's tons of room to improve :-/"
Andrew Morton replied, "kidding. We merged about 265 MM patches in 2.6.24-rc1: 482 files changed, 8071 insertions(+), 5142 deletions(-)". He added, "a lot of that was new functionality. That's easier to add than things which change long-standing functionality."

The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
