\n\u201eObr\u00e1zok ukradnut\u00fd zo z\u00e1padu na pril\u00e1kanie pozornosti\u201c<\/i><\/p>\n

V na\u0161ich predch\u00e1dzaj\u00facich \u010dl\u00e1nkoch sme sa podelili o to, ako pracova\u0165 s VDS<\/a><\/noindex> Windows Server Core 2019 na na\u0161om novom pl\u00e1ne UltraLight za 99 rub\u013eov mesa\u010dne. Pon\u00fakame \u010fal\u0161\u00ed sp\u00f4sob vyu\u017eitia tohto pl\u00e1nu. Tentoraz sa budeme zaobera\u0165 t\u00fdm, \u010do je lep\u0161ie vybra\u0165, ak potrebujete VPN pre leniv\u00fdch alebo statick\u00fa IP adresu, ktor\u00e1 je mimochodom pohodlnej\u0161ia na pou\u017e\u00edvanie namiesto Hamachi a in\u00fdch programov, ak m\u00e1te chu\u0165 hra\u0165 Hrdinov alebo Warcraft 3 v lok\u00e1lnej sieti. Nebudeme hovori\u0165 o nastaven\u00ed, ale o v\u00fdkonnosti.

Metodika testovania<\/h2>\n

\nRRAS a SoftEther boli vybran\u00e9 na z\u00e1klade jednoduchosti in\u0161tal\u00e1cie, podpory protokolu L2TP a mo\u017enosti spr\u00e1vy prostredn\u00edctvom GUi.<\/p>\n

Pre SoftEther a RRAS sa pou\u017e\u00edvalo pripojenie cez L2TP s predvolen\u00fdm k\u013e\u00fa\u010dom pomocou \u0161tandardn\u00fdch prostriedkov Windows. Ako sa to nastavilo, tak to aj bolo otestovan\u00e9.<\/p>\n

Ako opera\u010dn\u00fd syst\u00e9m pre SoftEther bola pou\u017eit\u00e1 Ubuntu 18.04 LTS, pre RRAS Windows Server Core 2019. V\u0161etky opera\u010dn\u00e9 syst\u00e9my dostali pred testovan\u00edm posledn\u00e9 aktualiz\u00e1cie k stavu z 21.11.2019.\u00a0<\/p>\n

Na virtu\u00e1lnu ma\u0161inu Hyper-V druh\u00e9ho pokolenia bolo nain\u0161talovan\u00fdch 1 GB RAM, rovnako ako obmedzenia na procesor. Poradie vykon\u00e1vania skupinov\u00fdch testov je nasledovn\u00e9:<\/p>\n

Na v\u0161etk\u00fdch 8 jadr\u00e1ch:<\/p>\n

    \n
  1. Bez obmedzen\u00ed<\/li>\n
  2. Obmedzenie 50%<\/li>\n
  3. Obmedzenie 25%<\/li>\n
  4. Obmedzenie 5%<\/li>\n
  5. Obmedzenie 1%<\/li>\n<\/ol>\n

    \nNa 4 jadr\u00e1:<\/p>\n

      \n
    1. Bez obmedzen\u00ed<\/li>\n
    2. Obmedzenie 50%<\/li>\n
    3. Obmedzenie 25%<\/li>\n
    4. Obmedzenie 5%<\/li>\n
    5. Obmedzenie 1%<\/li>\n<\/ol>\n

      \nNa jedno jadro:<\/p>\n

        \n
      1. Bez obmedzen\u00ed<\/li>\n
      2. Obmedzenie 50%<\/li>\n
      3. Obmedzenie 25%<\/li>\n
      4. Obmedzenie 5%<\/li>\n
      5. Obmedzenie 1%<\/li>\n<\/ol>\n

        \nNa v\u0161etk\u00fdch VPN serveroch boli aplikovan\u00e9 predvolen\u00e9 nastavenia a aktivovan\u00fd NAT. V\u0161etky virtu\u00e1lne ma\u0161iny sa nach\u00e1dzaj\u00fa na jednom hostite\u013eovi a na jednom a tom istom virtu\u00e1lnom prep\u00edna\u010di.<\/p>\n

        Na hodnotenie fungovania siete bolo vykonan\u00e9 testovanie medzi serverom a klientom bez pripojenia prostredn\u00edctvom VPN.<\/p>\n

        Test bol vykonan\u00fd pomocou TamoSoft Throughput Test v re\u017eime TCP only, pre tabu\u013eky a grafy boli odobran\u00e9 hodnoty \u201eave\u201c. \u00dadaje sa zbierali po\u010das 5 min\u00fat a 30 sek\u00fand pre ka\u017ed\u00fd test.<\/p>\n

        Pre lep\u0161ie pochopenie limitov oboch realiz\u00e1ci\u00ed, najprv otestujeme priepustnos\u0165 virtu\u00e1lneho prep\u00edna\u010da.<\/p>\n

        \"Bitka
        \nTak vyzerali v\u00fdsledky v teste. N\u00e1sledne bud\u00fa v\u0161etky v\u00fdsledky obalen\u00e9 v tabu\u013ek\u00e1ch.<\/p>\n

        Ako vid\u00edme, virtu\u00e1lny prep\u00edna\u010d nie je \u00fazkym miestom v testovan\u00ed a takmer dosahuje teoretick\u00fd limit 10 gigabitov.<\/p>\n

        \nObjem pam\u00e4te RAM, ktor\u00fa pou\u017e\u00edva SoftEther, vzr\u00e1stol s po\u010dtom jadier z 122 na 177 MB, ale st\u00e1le to je menej ako u RRAS.<\/p>\n

        Sama slu\u017eba RRAS zaber\u00e1 v pam\u00e4ti pribli\u017ene 200 megabajtov, bez zahrnutia celkovej spotreby syst\u00e9mu.<\/p>\n

        \"Bitka

Tak\u00e1to n\u00edzka v\u00fdkonnos\u0165 sa nikde nevyskytuje, ale samotn\u00e9 testovanie ukazuje, ak\u00fd dobre sa algoritmus naozaj \u0161k\u00e1luje v z\u00e1vislosti od po\u010dtu jadier.<\/p>\n

        Z\u00e1ver:<\/h2>\n

        \nPripoji\u0165 sa k SoftEther pri obmedzen\u00ed procesora nebolo mo\u017en\u00e9 na prv\u00fd pokus, najprv bolo potrebn\u00e9 zv\u00fd\u0161i\u0165 limit, pripoji\u0165 sa a potom zn\u00ed\u017ei\u0165 limit, \u010do uklad\u00e1 obmedzenia na jeho pou\u017eitie v ve\u013emi tenk\u00fdch prostrediach. RRAS sa v\u017edy prihl\u00e1sil okam\u017eite.<\/p>\n

        Ak m\u00e1te stroj s ve\u013ek\u00fdm po\u010dtom jadier, uprednostnite RRAS. Pre SoftEther m\u00f4\u017eete necha\u0165 aj 4 jadr\u00e1. Autor, keby ho pou\u017e\u00edval, by pre neho ponechal len jedno jadro.<\/p>\n

        \u010co a kde umiestni\u0165 \u2013 rozhodnite sa sami. Ak m\u00e1te 99 rub\u013eov na VPS<\/a><\/noindex> s Windows Server na palube, optim\u00e1lnou vo\u013ebou bude predsa len RRAS.\u00a0<\/p>\n
