Taky nějak nerozumím tomu, proč ne Hetzner, ale když ne on, tak Netcup nebo PHP-Friends.

Pozeram ten Netcup a vyzera to slubne. Hlavne ten root server co oni nazyvaju. Taka lepsia "VPS".
Ma tam niekto nieco? Dokazal by tam niekto hodit fio a otestovat? Ked nie tak to vyskusam. Ale nechapem preco, túto sluzbu nepoznam.

Kvůli diverzitě mám i něco u Vultr.com - jsou to amíci, ale datacentra mají i v EU. Nepočítej ale se stejným výkonem jako Contabo. Je to slabší.
Tak to uz musi system bootovat tak hodinu...
Mal som u contabo VPS a ten disk performance bol strasny, aj login na ssh trval okolo 10s (prave nainstalovana fedora), chvilu som to pouzival na nextcloud, siet bola v pohode, uzkym hrdlom bol prave disk.

Presiel som od nich k VPSfree a som zatial spokojny

Nevím, kde co jak máš, ale odezva na login je téměř okamžitá, do sekundy určitě, reboot do cca minuty. Oba, jak Vultr, tak Contabo.

Ne každý potřebuje pro svůj stroj hvězdný diskový výkon, někdo chce raději více RAM a CPU.

Každopádně, dívám se, že konkurence k Contabo už je a je docela zajímavá - i když je trochu dražší... Asi to promyslím...

Mozes mat aj 1TB RAM, aj CPU vykonu ale ked je disk pomalsi ako SD karta je ti to totalne k nicomu.

Na fóru Netcup mají dokonce tabulku, kde uživatelé měří IOPS.

A tu je ukazkovo vidiet aky podvod contabo to v podstate je a ze nieje hodne aby zato ludia platili ani 1 kč mesacne.

READ: bw=16.3MiB/s (17.1MB/s), 16.3MiB/s-16.3MiB/s (17.1MB/s-17.1MB/s)
WRITE: bw=4171KiB/s (4271kB/s), 4171KiB/s-4171KiB/s (4271kB/s-4271kB/s), io=820MiB (860MB)

16.3MiB/s na read a 4 MiB/s na write je nieco co sa neda akceptovat a akakolvek suma ktoru clovek musi zaplatit je uplne mimo.

Myslim ze jen ne zcela vite co merite. Pro nahodnych 1000 IOPS s velikosti 4k me ta sirka pasma prijde jako ocekavatelna hodnota. Pro jine typy zateze dava disk toho sameho serveru o dva rady vetsi propustnost.
Citace
Aj keby som zato dostaval peniaze je to proste nepouzitelne. Akakolvek najlacnejsia SD karta aj USB kluc je omnoho rychlejsie ako tento "virtualny server".
Asi dost zalezi na tom co myslite tim 'rychlejsi'. Neni pravda ze je to nepouzitelne. Realne to pouziva kazdy den rada uzivatelu. Dokazu si predstavit, ze vase aplikace nutne potrebuje o nekolik radu vice IOPS nez kolik vam ji Contabo kdy poskytne. Pak je pro vas ucel nebo aplikaci Contabo urcite nevhodne. Existuje ale mnoho pripadu, pro ktere jsou ta cisla  zcela dostatecna.
Citace
Uz cca 12 rokov dozadu som mal SSD v PC. Servre su daleko dolezitejsie a tam nemozu byt pomale disky a nieco co je pomalsie ako SD karta. To je masaker.

Myslim ze je jedno kolik mate SSD, nebo SD v PC. Servery klidne muzou mit disky s mene jak 1000 IOPS. Dokonce i servery vyhrazene jen pro vas.

Dotazujci se ostatne nepta po hostingu s vetsim vykonem, zrejme mu Contabo staci a zrejme i z pohledu propustnosti blokoveho zarizeni. Hleda alternativu v evrope kuli spolehlivosti, respektive zhorsujici se dostupnosti Contabo. Z toho lze usoudit, ze zrejme hleda neco s kratkou sitovou odezvou pro uzivatele v CR.
Moje mereni ani aplikace zvysene vypadky na Contabu v posledni dobe nezaznamenavaji. Presto verim ze je pozoruje. Contabo udrzby vypisuje https://contabo-status.com/ a zrejme mam zase jen stesti a me za posledni rok a pul zadna nezasahla.
A neporadim mu. Bylo by fajn, kdyby nejaky VPS hosting byl super spolehlivy a zaroven taky levny. Ale v case to jde trochu proti sobe.

Zdravim,

VPS na Contabo mam cca 2 roky a zatim jsem nemel zadny problem. Sice neprovozuji nic kritickeho, kde bych sledoval dostupnost nepretrzite, ale prvni rok jsem pristupoval nekolikrat denne a nedostupnost jsem nezazil.
