Kernel space: ELF prediction to speed application startup
,----[ Quote ]
| A new technique might make it faster to get started with a large application,
| by giving the kernel advance notice of what are most likely to be the
| program's commonly used memory pages

Comparing UBIFS And LogFS
,----[ Quote ]
| Following the recent announcement that UBIFS is nearly production ready, it
| was asked how UBIFS compares to LogFS. LogFS author Jörn Engel
| suggested, "both share similar design goals. Biggest difference is that ubifs
| works on top of ubi and depends on ubi support, while logfs works on plain
| mtd (or block devices) and does everything itself. Code size difference is
| huge. Ubi weighs some 11kloc, ubifs some 30, logfs some 8."

Plans for the Linux-next Tree

| is there any information you want from it?" Stephen Rothwell asked regarding
| the tree he started maintaining last month for tracking upcoming stable
| merges.

| openSUSE 10.3 (clean install, OSS/KDE): about 45 seconds

Ubuntu vs. That Other OS
,----[ Quote ]
| Both machines have the same exact specs, both have been used for the same
| time (to be fair I have tweaked the OS on the left quite a bit to optimize
| it). Ubuntu is already idle by the time the video ends; while the other PC
| takes 30 seconds more than what I’ve uploaded to idle the hard drive.

Is your Anti-Virus software slowing down your Vista boot time?
,----[ Quote ]
| When Microsoft first announced the feature set for Vista, one of the things
| they claimed was that you would actually have shorter startup times, but we
| later discovered that what they meant was that there would be power saving
| features that would make it easy to put your PC into sleep mode when you're
| not using it and quickly resume.

The Vista Sleep of Death

Windows Vista's Hideous Wakeup Support
,----[ Quote ]
| One thing we just can't wrap our mind about is the terrible,
| broken, and completely pitiful support for waking Vista up from
| a Deep Sleep or hibernation.' Any time you attempt to wake Vista
| up from Hibernation or "Deep Sleep" (S3-induced sleep mode), it
| dies. It's either a BSOD, or a driver error, or a broken network,
| no DWM, lack of sound... the list goes on, and on. So much for an
| operating system to "power" the future! (No pun intended!) That's
| with properly-signed drivers and no buggy software on
| multiple PCs...

Vista SP1 a Performance Dud
,----[ Quote ]
| After extensive testing of both RTM and SP1-patched versions of Windows
| Vista, it seems clear that the hoped-for performance fixes that Microsoft has
| been hinting at never materialized. Vista + SP1 is no faster than Vista from
| the RTM image.
|
| Bottom Line: If you've been disappointed with the performance of Windows
| Vista to date, get used to it. SP1 is simply not the panacea that many
| predicted. In the end, it's Vista's architecture - not a lack of tuning or
| bug fixes - that makes it perform so poorly on systems that
| were "barn-burners" under Windows XP.

Vista Irritations

| According to this Slashdot article, copying, moving and deleting

| compressed file under Vista is like watching paint dry/grass grow

Vista: Slow and Dangerous
,----[ Quote ]
| Most of the time I spent testing Vista was with sluggish pre-release
| versions. I expected things to improve when I ran the finished software
| on PCs configured for the new Windows version. I now realize that
| Vista really is slow unless you throw a lot of hardware at it.
| Microsoft claims it will run with 512 megabytes of memory. I had
| recommended a minimum of a gigabyte, but 2 GB is more like it if
| you want snappy performance.
|
| [...]
|
| The most exasperating thing about Vista, though, is the security
| feature called User Account Control. UAC, satirized in an Apple
| ad as a security guy who constantly interrupts a conversation,
| appears as a pop-up asking permission before Windows...
