Не знам дали тук има питонаджии, но може да се пробват.

Привет!

От едно известно време администрирам един сървър (дълга история, наследен ми е).

Обаче ми направи впечатление че дисковата активност е бавна.

Това е хардуера (вързан в RAID 1).

Ето и реални тестове на 2 различни машини.

$ time gunzip -t -vvvvvvvvvvv linux-2.6.35.tar.gz
linux-2.6.35.tar.gz:    OK

real   0m2.695s

Това е на моята каруца (напълно нормален MacPro)

-----------
# time gunzip -t -v linux-2.6.35.tar.gz

Това е на uber страшния сървър дето на хартия параметрите му са 2-3 пъти по-добри. Общо взето банален тест - да разархивираме 88 МБ файл за да получим 412 МБ такъв.

$ time gunzip linux-2.6.35.tar.gz

Това е при мен. Общо взето нормална скорост.

Тук гледам едно влачене... дето не мога да си го обясня...

Нещата са много сложни и заплетени и не мога да си обясня по никакъв начин бавната дискова активност.
Та въпроса ми е има ли някакъв бенчмарк който да го пусна на линукса и на osx-а да ги бенчна?

Ето ТАКА трябва да изглежда Линукс.

Така - unboxing + работата на устройството:




















































Изработката е перфектна. Досега толкова малък STB не съм виждал.

Засега забелязах само един дефект - не може да се управлява силата на звука от STB-то.

AMD Discards ATI Brand Name

http://mashable.com/2010/08/30/amd-ditches-ati/

Advanced Micro Devices (AMD) has decided to kill its ATI brand name, judging that the names of its graphics chip products, such as Radeon and FirePro, in combination with the AMD brand, are familiar enough to consumers to stand on their own.

AMD had bought graphics chip manufacturer ATI for $5.4 billion back in 2006., in one of the biggest acquisitions ever in the semiconductor industry, and internally, ATI was renamed to AMD Graphics Product Group.

However, due to the strength of the ATI brand (and the long-time rivalry with competitor Nvidia), the ATI name survived to this day, often causing tech journalists trouble as they had to squeeze three brand names – AMD, ATI and Radeon – in one title.

Now, after conducting market research which showed that the AMD and Radeon brand are strong enough, AMD has decided it doesn’t need the name ATI anymore. Current products will not be renamed, but we can expect to see the first AMD Radeon products later this year.

T.e. вече ще псуваме освен АМД процесорите и АМД видеокартите. Нека пазителя на АМД РОКО__ се появи сега и пламенно ги защити!

Геноцид!

Привет.

Днес се опитах да инсталирам Poptop на FC6. И успях.

Ето част от лога при успешно свързване:
