Kungani ukulanda kwe-VPN kulinganiselwe ukulayisha kweseva

Iklayenti likhombisa isixhumanisi sokulanda esisheshayo, iseva ihlezi kuxhumano lwe-fiber, kanti ukudlulisa kusagunda. Inombolo abantu abayiqhathanisayo ngokuvamile yileyo ephrintiwe ohlelweni lweklayenti, kuyilapho iphakethe empeleni liqala ukweqa isixhumanisi sokuphuma seseva. Leso sixhumanisi yisabelomali okumele ukudlulisa kungene kuso. Kuxhumano lwasekhaya oluncane yinombolo encane kunazo zonke endleleni.

Inombolo oyifundile yayisekuhambeni okungalungile

Ukulanda kwaya kuklayenti ekude kusebenzisa umthamo wokulayisha ekugcineni kweseva kwethumbu. Izilinganiso zokulanda zeseva ezikhangisiwe zichaza ukuqondana okuphambene futhi azisho lutho ngalokhu. Ukungalingani okufanayo kuyaphenduka lapho iklayenti lilayisha, yingakho uhlangothi olulodwa lungazwakala lukuhle kuyilapho olunye lungasetshenziswa.

Izindleko zokugoqa nanoma yikuphi ukuhamba okuncintisanayo zisebenzisa ingxenye yaleso sabelomali. Akukho kukodwa kwazo okubonakala ekuhlolweni kwesivinini okukala iklayenti kuphela.

Bhala indlela njengesabelomali

Bhala uhlu lwazo zonke izingqinamba okumele iphakethe lizweqe futhi unikeze ngayinye inombolo ngeyunithi efanayo. Ukulethwa kusuka emthonjeni, ukucubungula kuseva, isixhumanisi sokulayisha seseva, indlela ephakathi, isixhumanisi sokulanda seklayenti nokucubungula kuklayenti konke kuyasebenza. Isivinini esingasetshenziswa yileso esincane kunakho konke ngemva kokukhipha izindleko, futhi akukho kulungisa okungaphezu kwalelo khwanisi okushintsha umphumela. Bhala uhlu ngaphambi kokukala, ngoba likutshela ukuthi iyiphi inombolo okungafanele uyikholwe.

Ngesixhumanisi sokulayisha seseva esingu-20 Mbit/s nesixhumanisi sokulanda seklayenti esingu-100 Mbit/s, iseva inciphisa ukudlulisa kusenesikhathi kakhulu ngaphambi kokuba iklayenti liqaphele. Izindleko nanoma yikuphi ukudlulisa okusikhathi esisodwa kuthatha ingxenye eyengeziwe, futhi isixhumanisi sokulayisha esigcwele sibambezela neziqinisekiso, okunciphisa isivinini sokudlulisa kwe-TCP ngaphansi kwekhwanisi eliluhlaza. Akukho kulemithelela emibili evelayo ekuqhathanisweni kwezinhlelo.

Hlukanisa amamegabhithi namamegabhayithi, futhi usho ukuthi ingabe inombolo ngayinye ikala ukuhamba kwesixhumanisi esifihliwe noma umthwalo wohlelo lokusebenza. Ukuhlanganisa lokhu okubili yisizathu esivame kakhulu sokuthi isabelomali sibonakale singahlangani. Faka ilebula kunombolo ngayinye ngeyunithi yayo nendawo yokukala.

Lapho ibhodi likubiza khona ngempela

Lapho isixhumanisi sokufinyelela sesikhulu ngokwanele, ihadiwe yendawo yokugcina iyabonakala, futhi yilapho kuphela iprosesa ibaluleka. Khomba imodeli, ukuhlelwa kwezixhumanisi kanye nokuqaliswa okusetshenziswayo. Ukuqaphela ngebhasi elabiwe lebhodi lakudala akuchazi zonke izinguqulo ezilandelayo.

Qhathanisa izindlela zokucubungula ngazinye esikhundleni sesilinganiso esisodwa se-CPU. Umthwalo ophelele olinganiselayo ungafihla ikhori eyodwa egcwele eyenza wonke umsebenzi ngephakethe ngalinye, futhi imvamisa yewashi ayidluli phakathi kwemiklamo yeprosesa njengephuzu lokusebenza. Izinga lamaphakethe libalulekile njengokugeleza, ngoba amaphakethe amancane abiza kakhulu ngebhayithi kunamakhulu. Kala ngosayizi bamaphakethe umthwalo wakho womsebenzi oyisebenzisa ngempela.

Imingcele yokushisa namandla nayo inquma ukuziphatha okuhlala isikhathi eside. Ukuqhuma okufushane kungabonakala kuhle kakhulu kuyilapho ukudlulisa kwemizuzu eyishumi kuncipha, yingakho isilinganiso semizuzwana embalwa siyisiqondiso esibi sokugcinwa kwasemva kwesikhathi ebusuku.

Imihlahlandlela yokusebenza yomthengisi ihlukanisa ububanzi bezinga lokufinyelela, i-CPU, ukucubungula amaphakethe, ukuthutha kanye nosayizi wephakethe kwaba imikhawulo ehlukene. Kufanelekile ukuyifunda ngaphambi kokushintsha i-cipher, ngoba ukushintsha i-cipher akuvamisile ukuhambisa umngcele ongakaze ube umkhawulo.

Kala ngaphambi kokushintsha i-cipher

Gijimisa ukuhlolwa okuqondisayo okubika isivinini esitholakale ngempela ngethumbu, bese ugijimisa lokho kuhlolwa okufanayo kusixhumanisi esiluhlaza ukuze kuqhathaniswe. Umehluko phakathi kwalezo zinombolo ezimbili yizindleko zethumbu, futhi elincane kumakhwanisi amabili likutshela ukuthi yimuphi umngcele okumele uhlaselwe.

Gcina inqubomgomo yezokuphepha iphelele ngenkathi uqhathanisa. Umphumela wakudala otholwe nge-cipher ebuthakathaka noma ibhodi eline-overclock awusona isu lokusetshenziswa kwamanje.

iperf3 -c 10.44.0.1 -R -t 30
iperf3 -c 10.44.0.1 -t 30
ethtool eth0 | grep -i speed

Gcina imiphumela eqondisayo eduze nokuqaphela kwendawo yokugcina kokugijima okufanayo. Ushintsho olulandelayo kufanele luhlose ikhwanisi elikaliwe hhayi ingxenye ebonakala incane kakhulu ephepheni lemininingwane.
