\n\u201eImagine furtiv\u0103 de pe vest pentru atragerea aten\u021biei\u201d<\/i><\/p>\n

\u00cen articolele noastre anterioare, am discutat despre cum s\u0103 lucr\u0103m cu VDS<\/a><\/noindex> Windows Server Core 2019 pe noul nostru plan UltraLight la 99 de lei pe lun\u0103. Oferim o alt\u0103 metod\u0103 de utilizare a acestui plan. De data aceasta, vorbim despre ce s\u0103 alegi mai bine, dac\u0103 ai nevoie de un VPN pentru lene\u0219i sau de un IP static, care este, de altfel, mai u\u0219or de utilizat \u00een locul Hamachi \u0219i altor solu\u021bii similare, dac\u0103 \u00ee\u021bi dore\u0219ti foarte mult s\u0103 joci Heroes sau Warcraft 3 \u00een re\u021bea local\u0103. Nu vom vorbi despre configurare, ci despre performan\u021b\u0103.

Metodologia de testare<\/h2>\n

\nRRAS \u0219i SoftEther au fost alese pe baza simplit\u0103\u021bii instal\u0103rii, suportului pentru protocolul L2TP \u0219i posibilit\u0103\u021bii de gestionare prin GUi.<\/p>\n

Pentru SoftEther \u0219i RRAS s-a utilizat conectarea prin L2TP cu cheie comun\u0103 prin instrumentele standard Windows. A fost instalat \u0219i apoi testat.<\/p>\n

Sistemul de operare pentru SoftEther este Ubuntu 18.04 LTS, iar pentru RRAS este Windows Server Core 2019. Toate sistemele de operare au primit cele mai recente actualiz\u0103ri p\u00e2n\u0103 la data de 21.11.2019 \u00eenainte de teste.\u00a0<\/p>\n

Pe ma\u0219ina virtual\u0103 Hyper-V de a doua genera\u021bie, au fost instalate 1 GB RAM, precum \u0219i limite pentru procesor. Ordinea de execu\u021bie a grupurilor de teste este urm\u0103toarea:<\/p>\n

Pentru toate 8 nucleele:<\/p>\n

  2. Limit\u0103 de 50%<\/li>\n
  3. Limit\u0103 de 25%<\/li>\n
  4. Limit\u0103 de 5%<\/li>\n
  5. Limit\u0103 de 1%<\/li>\n<\/ol>\n

    \nPentru 4 nuclee:<\/p>\n

    3. Limit\u0103 de 25%<\/li>\n
    4. Limit\u0103 de 5%<\/li>\n
    5. Limit\u0103 de 1%<\/li>\n<\/ol>\n

      \nPentru un singur nucleu:<\/p>\n

        \n
      1. Sin restricciones<\/li>\n
      2. Limit\u0103 de 50%<\/li>\n
      3. Limit\u0103 de 25%<\/li>\n
      4. Limit\u0103 de 5%<\/li>\n
      5. Limit\u0103 de 1%<\/li>\n<\/ol>\n

        \nPe toate serverele VPN au fost aplicate set\u0103rile din cutie \u0219i a fost activat NAT. Toate ma\u0219inile virtuale se afl\u0103 pe un singur host \u0219i pe acela\u0219i switch virtual.<\/p>\n

        Pentru a evalua func\u021bionarea re\u021belei, s-a efectuat un test \u00eentre server \u0219i client f\u0103r\u0103 conexiune prin VPN.<\/p>\n

        Testul a fost realizat cu ajutorul TamoSoft Throughput Test \u00een modul TCP only, pentru tabele \u0219i grafice au fost luate valorile \u201emedii\u201d. Datele au fost colectate timp de 5 minute \u0219i 30 de secunde pentru fiecare test.<\/p>\n

        Pentru a \u00een\u021belege mai bine limitele ambelor implement\u0103ri, s\u0103 test\u0103m mai \u00eent\u00e2i capacitatea de transmitere a switch-ului virtual.<\/p>\n

        \"B\u0103t\u0103lia
        \nA\u0219a au ar\u0103tat rezultatele \u00een programul de testare. Ulterior, toate rezultatele vor fi grupate \u00een tabele.<\/p>\n

        Dup\u0103 cum vedem, switch-ul virtual nu este un punct slab \u00een testare \u0219i aproape atinge limita teoretic\u0103 de 10 gigabi\u021bi.<\/p>\n

        \nAici vedem clar care solu\u021bie se scalabilizeaz\u0103 cel mai bine \u00een func\u021bie de num\u0103rul de nuclee. Reduc\u00e2nd performan\u021ba fiec\u0103rui nucleu, RRAS a compensat pierderile prin cantitate, ceea ce SoftEther nu a reu\u0219it s\u0103 fac\u0103.<\/p>\n

        \"B\u0103t\u0103lia
        \nCantitatea de memorie RAM consumat\u0103 de SoftEther a crescut odat\u0103 cu num\u0103rul de nuclee, de la 122 la 177 MB, dar totu\u0219i r\u0103m\u00e2ne mai mic\u0103 dec\u00e2t cea a RRAS.<\/p>\n

O astfel de performan\u021b\u0103 sc\u0103zut\u0103 nu se \u00eent\u00e2lne\u0219te nic\u0103ieri, dar testarea \u00een sine arat\u0103 c\u00e2t de bine se scaleaz\u0103 algoritmul \u00een func\u021bie de num\u0103rul de nuclee.<\/p>\n

        Concluzie:<\/h2>\n

        \nConectarea la SoftEther cu restric\u021bie pe procesor nu a reu\u0219it din prima, a fost necesar mai \u00eent\u00e2i s\u0103 cresc limita, s\u0103 m\u0103 conectez \u0219i abia apoi s\u0103 reduc limita, ceea ce impune o restric\u021bie asupra instal\u0103rii sale \u00een medii foarte restr\u00e2nse. RRAS s-a conectat \u00eentotdeauna instantaneu.<\/p>\n

        Dac\u0103 ave\u021bi o ma\u0219in\u0103 cu un num\u0103r mare de nuclee, prefera\u021bi RRAS. Iar pentru SoftEther, pute\u021bi l\u0103sa chiar \u0219i 4 nuclee. Autorul, dac\u0103 l-ar folosi, ar l\u0103sa pentru el doar un singur nucleu.<\/p>\n

        Ce \u0219i unde s\u0103 plasa\u021bi \u2013 decide\u021bi singuri. Dac\u0103 ave\u021bi 99 de ruble pe VPS<\/a><\/noindex> cu Windows Server la bord, alegerea optim\u0103 va fi totu\u0219i RRAS.\u00a0<\/p>\n
