Swap Over NFS
,----[ Quote ]
| "The problem with swap over network is the generic swap problem: needing
| memory to free memory. Normally this is solved using mempools, as can be seen
| in the BIO layer," explained Peter Zijlstra. "Swap over network has the
| problem that the network subsystem does not use fixed sized allocations, but
| heavily relies on kmalloc(). This makes mempools unusable."
|
| The first fifteen patches set up a generic framework for reserving memory.
| Patches 16-23 actually put the framework to use on the network stack.

Windows ReadyBoost Doesn't Deliver
,----[ Quote ]
| I don't know if this is a problem with Vista or the drive, but it is
| annoying to have to check to see if it off and then turn it back on
| again. Sometimes the disk space is used after ReadyBoost is off,
| forcing me to format the flash drive again before turning it back on.

Vista, iTunes and ReadyBoost do not play well
,----[ Quote ]
| The only solution for the problem is to unplug your ReadyBoost drive, close
| and restart iTunes and then play back your video normally. I have
| replicated this no less than 30 times on my laptop with a ReadyBoost
| drive plugged in. Unplugging the drive never fails to fix the problem
| and plugging it in never fails to cause the problem.

Microsft Vista's ReadyBoost: Is worth the hype??
,----[ Quote ]
| The performance gain in second time 18seconds vs 5:30 seconds was
| due to SuperFetch technology which has nothing to do with ReadyBoost.
|
| Then Microsoft Word 2007 was loaded. Without ReadyBoost for first time
| took 5 seconds and with ReadyBoost took 26 seconds :-s.
|
| [...]
|
| Is ReadyBoost meant to work this way :-/ Is this a Flaw in Vista or like
| Microsoft is doing making Flaws as Features. Is this also a feature??
|
| The mystery continues....
