Vi erbjuder ytterligare ett s\u00e4tt att anv\u00e4nda detta abonnemang. Denna g\u00e5ng handlar det om vad som \u00e4r b\u00e4st att v\u00e4lja om du beh\u00f6ver en VPN f\u00f6r lata eller en statisk IP-adress, som f\u00f6r \u00f6vrigt \u00e4r enklare att anv\u00e4nda ist\u00e4llet f\u00f6r Hamachi och allt annat om du verkligen vill spela Heroes eller Warcraft 3 i ett lokalt n\u00e4tverk. Vi kommer inte att prata om konfigurationen, utan vi fokuserar p\u00e5 prestanda.

Testmetodik<\/h2>\n

\nRRAS och SoftEther valdes utifr\u00e5n enkel installation, st\u00f6d f\u00f6r L2TP-protokollet och m\u00f6jlighet till hantering via GUi.<\/p>\n

F\u00f6r SoftEther och RRAS anv\u00e4ndes anslutning via L2TP med gemensam nyckel genom Windows standardverktyg. Det installerades och testades som det var.<\/p>\n

Som operativsystem f\u00f6r SoftEther anv\u00e4nds Ubuntu 18.04 LTS och f\u00f6r RRAS Windows Server Core 2019. Alla operativsystem fick de senaste uppdateringarna per den 21.11.2019 innan testerna.\u00a0<\/p>\n

F\u00f6r den andra generationens Hyper-V virtuell maskin installerades 1 GB RAM och processorlimiter. Ordningen f\u00f6r att utf\u00f6ra testerna \u00e4r som f\u00f6ljer:<\/p>\n

        \nP\u00e5 alla VPN-servrar anv\u00e4ndes standardinst\u00e4llningarna och NAT var aktiverat. Alla virtuella maskiner ligger p\u00e5 samma v\u00e4rd och p\u00e5 samma virtuella switch.<\/p>\n

        F\u00f6r att bed\u00f6ma n\u00e4tverksarbetet genomf\u00f6rdes tester mellan servern och klienten utan VPN-anslutning.<\/p>\n

        Testet genomf\u00f6rdes med hj\u00e4lp av TamoSoft Throughput Test i endast TCP-l\u00e4ge, f\u00f6r tabeller och diagram anv\u00e4ndes genomsnittsv\u00e4rdena. Data samlades in under 5 minuter och 30 sekunder f\u00f6r varje test.<\/p>\n

        F\u00f6r att b\u00e4ttre f\u00f6rst\u00e5 begr\u00e4nsningarna i b\u00e5da implementeringarna kommer vi f\u00f6rst att testa genomstr\u00f6mningskapaciteten f\u00f6r den virtuella switchen.<\/p>\n

        \nH\u00e4r ser vi tydligt vilken l\u00f6sning som b\u00e4st skalas med antalet k\u00e4rnor. Genom att minska prestandan hos varje k\u00e4rna kompenserade RRAS f\u00f6r f\u00f6rlusterna genom m\u00e4ngden, n\u00e5got som SoftEther inte gjorde.<\/p>\n

        Slutsats:<\/h2>\n

        \nAtt ansluta till SoftEther med begr\u00e4nsad processor gick inte p\u00e5 f\u00f6rsta f\u00f6rs\u00f6ket; jag var tvungen att f\u00f6rst \u00f6ka begr\u00e4nsningen, ansluta och sedan s\u00e4nka begr\u00e4nsningen, vilket inf\u00f6r ett hinder f\u00f6r dess installation i mycket begr\u00e4nsade milj\u00f6er. RRAS loggade alltid in omedelbart.<\/p>\n

        Om du har en maskin med m\u00e5nga k\u00e4rnor, v\u00e4lj RRAS. F\u00f6r SoftEther kan du \u00e4ven anv\u00e4nda 4 k\u00e4rnor. Om f\u00f6rfattaren skulle anv\u00e4nda den, skulle han l\u00e4mna endast en k\u00e4rna \u00e5t den.<\/p>\n

        Vad och vart du ska placera \u2013 avg\u00f6r sj\u00e4lv. Om du har 99 rubel p\u00e5 VPS<\/a><\/noindex> med Windows Server ombord, \u00e4r RRAS fortfarande det optimala valet.\u00a0<\/p>\n
