Christian Ude, bývalý dlouholetý starosta Mnichova, v rozhovoru pro německý Linux Magazin vzpomíná na projekt LiMux, kdy město přešlo na vlastní linuxovou infrastrukturu a OpenOffice.org (posléze LibreOffice), ale příští vládnoucí koalice se rozhodla vrátit se k produktům Microsoftu.

Uživatelé Linuxu ve VirtualBoxu obvykle instalují Přídavky pro hosta (Guest Additions) pro lepší podporu emulovaného hardwaru. Brzy už ale nebudou přídavky potřebné. Ovladač vboxguest se dostal již do Linuxu 4.16 v dubnu loňského roku. Včera vydal Linus Torvalds Linux 5.4-rc7 (LKML). Přidán byl ovladač vboxsf (VirtualBox Shared Folder) pro sdílené složky.

Webový prohlížeč Mozilla Firefox 1.0 byl vydán před 15 lety, 9. listopadu 2004. Článek v magazínu Fast Company připomíná vývoj zastoupení Firefoxu mezi uživateli webu, jeho propad ve prospěch Google Chrome a následný vývoj, zvláště orientaci Mozilly na ochranu soukromí uživatelů a hodnoty formulované v manifestu.

Srovnání i5-2400@3.10GHz s Atomem C2750@2.40GHz

10.7.2015 01:00 | Přečteno: 1618× | poslední úprava: 10.7.2015 16:33

Dostal jsem se k serveru se základní deskou SuperMicro A1SA7-2750F osazenou osmijádrovým procesorem Intel(R) Atom(TM) CPU C2750 @ 2.40GHz a paměťmi DDR3 taktovanými na 1600MHz. A protože do budoucna uvažuji o tom, že ve svém domácím serveru vyměním základní desku za něco s podporou IPMI, řekl jsem si, že zkusím porovnat výkon se stávajícím HW, což je deska Gigabyte Z77MX-D3H osazená čtyřjádrovým procesorem Intel(R) Core(TM) i5-2400 CPU @ 3.10GHz bez hyperthreadingu a DDR3 RAM taktovanou na 1333 MHz.
Upozornění: v článku jsou jen surová data. Pokud chcete nějaké předžvýkané závěry, je pro vás zbytečné to otevírat...

Testování jsem - s ohledem na cílové využití - prováděl v KVM virtuálu, kterému jsem přidělil 4GB RAM a všechna dostupná jádra. Operačním systémem byl s výjimkou posledního testu aktuální Gentoo Linux; poslední test jsem spouštěl v Debianu Jessie v LXC kontejneru.

Jako první přišel na řadu sysbench, nejprve spuštěný v jednom vlákně a pak v osmi.

Následovala klasická kompilace linuxového jádra, konfigurační soubor byl v obou případech stejný. Nejprve jsem kompiloval s parametry "-j5 -l5" (protože i5-2400 je čtyřjádro), posléze s "-j9 -l9" (protože Atom má osm jader).

Edit: Na návrh Michala Kubečka dole v diskusi jsem zkusil kompilovat na tmpfs (původně jsem si jen adresář se zdrojáky jádra natáhl do cache); na i5 byly rozdíly minimální, na Atomu se mi ovšem podařilo stáhnout původní skoro čtyřminutový náskok i5 téměř na nulu. Panu Kubečkovi díky za nakopnutí. Před samotným spuštěním genkernelu jsem ještě pokaždé spouštěl make mrproper a make clean, swap byl během kompilace vypnutý.

i5-2400:

Zaujalo mě, že šifrování větších bloků pomocí HW akcelerace se mezi oběma procesory liší znatelně méně než bez ní.

No a nakonec jsem vyzkoušel jednovláknové kódování devatenácti minut zvuku z WAVu do MP3 pomocí Lame.

i5-2400:

# time lame --preset standard Hergest\ Ridge\ \(Part\ One\).wav
...

Před samotnou kompilací jsem pro jistotu spustil 'tar -cp linux-4.0.5-gentoo | cat > /dev/null', aby toho bylo co nejvíc v cachi a tudíž aby byl proces co nejméně zpomalován přístupem na disk.

Nebylo by jednodušší to rovnou překládat na tmpfs, aby to disk neovlivňoval vůbec? (A k čemu je tam dobrý ten cat?)

Vzhledem k tomu, že jste to spouštěl ve virtuálu, což znamená dva operační systémy, kde mohly další procesy náhodně ovlivňovat výsledky, bylo by vhodné aspoň spustit každý test víckrát a uvést aspoň průměr a směrodatnou odchylku.

Ohledně prezentace: je to strašně nepřehledné. Doporučoval bych do textu dát jen tabulku s výsledky jednotlivých testů a kompletní výstupy přiložit zvlášť, aby se do nich čtenář podíval až když ho budou zajímat detaily.

Určitě mělo, to porovnání je rozhodně zajímavé. Jen jsem upozornil na některé věci, které se daly udělat lépe. Hlavně ta prezentace výsledků, zorientovat se ve výstupech jednotlivých příkazů a vytáhnout z nich to podstatné chvíli trvá; kdyby tam byla přehledná tabulka a pak zvlášť detailní logy, bylo by to mnohem lepší.

Jinak na těch "dvou systémech" v danou chvíli běžel v podstatě jen rsyslog a SSH (+QEMU bez jakýchkoli dalších nástrojů na fyzickém stroji). Vícekrát jsem spouštěl sysbench a OpenSSL a lišily se v podstatě jen o desetiny vteřiny.

Tohle je na dnešních systémech bohužel čím dál méně pravda. Ještě tak před 7-8 lety jsem na školeních ukazoval výstup ps a komentoval, že přestože systém (s KDE) běží už několik hodin, jsou tam jen jeden nebo dva procesy, které nasbíraly přes sekundu času CPU (a žádný přes dvě). Dnes už by to vypadalo výrazně jinak.

Když jsou výsledky tak zřetelně odlišné, jako je to ve většině testů tady, tak to moc nevadí. Pokud ale někdy budete dělat test, kde budou jen malé rozdíly mezi dvěma variantami, může to výsledky dost ovlivnit.

Teď si nejsem jistý, co není pravda. Je tam základní Gentoo a ve výpisech procesů opravdu vidím jen init (OpenRC), rsyslogd, sshd a udev, na fyzickém stroji ještě qemu-system-x86. Samozřejmě na takovém Ubuntu by to vypadalo jinak.

No já už právě kvůli tomu čím dál častěji používám Gentoo, protože to je stále ještě relativně čisté. A pokud nepotřebuju poslední verze balíčků, tak CentOS6, ten tu s námi ještě pár let bude a při instalaci bez instalátoru člověk také dostane relativně čistý systém. Co budu dělat, až i tyhle poslední ostrůvky zmizí, zatím nevím...

Pokud je málo paměti, tak i data na tmpfs mohou být odswapována, takže pokud se dělají podobné testy, tak je vhodné před testem swap vypnot. Případně se může místo tmpfs použít ramfs, ten je v jádrech přítoment automaticky (viz cat /proc/filesystems), ale nemá kvóty, limity a hlavně možnost odlložit data do swapu. Tudíž je velmi snadné jeho pomocí dostat systém do stavu, kdy dojde paměť a jádro s tím nemůže nic udělat, navíc se paměť zabraná ramfs (i tmpfs) jeví jako disková cache, tudíž ji mnoho "paměťometrů" ignoruje.

Ono je otazka, zda dnes naopak vubec jeste swap zapinat.

Presne tak, server by mal mat dostatocne mnozstvo RAM na veci, co tam bezia. To moze byt napriklad v pripade mail servera aj 1 GB. Na mnohych serveroch swap roky nepouzivam.

Ano. Leakující nebo dlouho idlící aplikace se odswapují a volná paměť se může použít pro pagecache pomalých disků.

Zkouším to teď znova na tmpfs, na i5 jsou rozdíly maximálně o tři vteřiny, ale na Atomu "osmijádrová" kompilace dotáhla náskok a v podstatě se neliší od i5. Dokončuju ještě test na čtyřech jádrech, pak to doplním do článku.

Díky za zajímavé srovnani sam mám C2750 v domácím serviku už rok a jsem moc spokojen. Mám Asrock C2750d4i. Spotřeba naprosto parádní i kdyz ne priliz rozdílná v režimu idle/load.

Mimochodem, zkusil jsem si ten benchmark OpenSSL spustit na počítači s Xeonem X3440, který podle specifikací nemá podporu AES-NI (a nehlásí ji ani v /proc/cpuinfo). Jak je možné, že to s parametrem -evp jede víc než dvakrát tak rychle?

Aha, zpět, já měl nějak zafixováno, že -evp zapíná AES-NI, ale ve skutečnosti to zapíná nějaké další kryptografické funkce (které umí AES-NI využít, ale fungují i bez něj).

Pěkné srovnání, pro běžného uživatele je ale trochu výhodnější tohle: Intel Core i5-2400@3.10GHz vs Atom C2750@2.40GHz. Od pohledu je jasné, že tyhle procesory jsou neporovnatelné...

Co si představujete pod pojmem "neporovnatelné"? :-)

Rok 2010 vs. 2014, TDP 95 W vs. 20 W, 4 jádra vs. 8 jader…

Porovnat se dá samozřejmě všechno, ale u příliš odlišných věcí nedává výsledek moc velký smysl.

Jak jsem psal, srovnával jsem si to z čistě praktického důvodu, protože prostě uvažuju o nahrazení jednoho druhým. Takže pro mě to smysl má...

Jenze od zacatku je jasne, ze to bude vykonostne krok dolu. Pokud porovnavat, tak bych k tomu pridal procesor z "Atomoveho" segmentu: Athlon 5350. Pri TDP 25 W ma oproti Atomu vyssi vykon jednoho threadu, takze pokud nedojde k vyrazne paralelizaci, bude se zdat rychlejsi. Navic ma dve vyhody - integrovanou grafiku a to, ze jde o samostatny modul, neni tedy problem jej vymenit, pripadne jej zasadit do jine desky.

Panebože...

Já si to kvůli vám fakt kupovat nebudu. Já potřebuju úspornou serverovou desku s IPMI a rozumným výkonem ve více vláknech (který je s tím i5 srovnatelný, což mě mile překvapilo). To mi tahle věc splňuje. Dělal jsem si srovnání pro sebe a když už jsem ho měl, tak jsem ho vyblil i sem. Kdybych věděl, že kolem toho bude taková kovbojka, vyprdnul bych se na to...

To je tak když lidi řeší víc čísla než užití dané věci. Já jsem teď taky koupil na jeden účel výrazně slabší hardware s ohledem na jiné výhody.
Já už tu vlastně ani nejsem. Abclinuxu umřelo.

A grafika je mi na serveru k čemu, že jsem tak smělý? I bez toho základního VGAčka bych se obešel, když tam budu mít k dispozici BMC s možností připojit se na sériovou konzoli.

Jo, jsou zdejší uživatelé ukňouraní čůráci. Ještě štěstí, že tu není kyknos.
