Indl\u00e6sningstiden for <a href=\"https:\/\/webhosting.de\/da\/5-gruende-eine-website-zu-erstellen\/\">Websted<\/a> meget tydeligt fra et aktiveret chaching-plugin. Det gl\u00e6der b\u00e5de bes\u00f8gende og s\u00f8gemaskiner.<\/p>\n<p>Et af disse plugins til forbedring af indl\u00e6sningstider er W3 Total Cache Plugin. Hvad dette plugin har i detaljer, og hvilke fordele og ulemper det medf\u00f8rer, vil du l\u00e6re i det f\u00f8lgende.<\/p>\n<p>Hvorfor et plugin til caching?<\/p>\n<p>Selvf\u00f8lgelig har ikke alle bloggere n\u00f8dvendigvis brug for et s\u00e5dant plugin. Mange webmastere forbedrer ogs\u00e5 webstedets indl\u00e6sningstider manuelt, f.eks. ved at reducere st\u00f8rrelsen af billederne eller ved at reducere st\u00f8rrelsen af kildeteksten. Dette er ofte nok til at reducere indl\u00e6sningstiden. Det skal ogs\u00e5 siges, at den <a href=\"https:\/\/webhosting.de\/da\/webspace-2\/\">Webspace<\/a> har ogs\u00e5 en stor andel i pr\u00e6stationen. Afh\u00e6ngigt af udbyder og servicepakke varierer ydelsen betydeligt. Dette afspejler sig ofte ogs\u00e5 i prisen.<\/p>\n<p>Caching-plugin kan ogs\u00e5 v\u00e6re nyttigt, hvis webstedet ikke er designet til h\u00f8j ydeevne. Eventuelle mangler i indl\u00e6sningstiden kan kompenseres af en s\u00e5dan plug-in. Som regel fungerer plug-in'et p\u00e5 en s\u00e5dan m\u00e5de, at webstedet lagres midlertidigt som en HTML-fil i et bestemt tidsrum. Det betyder, at webstedet ikke bliver spurgt igen. <a href=\"https:\/\/webhosting.de\/da\/datenbank-server\/\">Database<\/a>n\u00e5r den bes\u00f8gende vender tilbage til webstedet. Databasen bliver s\u00e5ledes s\u00e5 at sige aflastet. Denne praksis kaldes normalt sidecache eller diskcache.<\/p>\n<p>W3 Total Cache-pluginet har ogs\u00e5 et par andre caching-muligheder, som forklares mere detaljeret i slutningen af artiklen.<\/p>\n<p>fordele og ulemper<\/p>\n<p>Som allerede n\u00e6vnt har s\u00e5danne plugins forskellige fordele og ulemper. Anvendelsen b\u00f8r derfor v\u00e6re velovervejet.<\/p>\n<p>Fordele<\/p>\n<p>En meget stor fordel er, at brugen af et caching-plugin kan spare betydeligt p\u00e5 serverens str\u00f8m. Dette sparer ressourcer i forbindelse med udnyttelsen af databasen og serverens CPU. S\u00e5 de bes\u00f8gende f\u00e5r det cachede websted vist i en vis periode.<\/p>\n<p>Dette giver ogs\u00e5 en fordel med hensyn til omkostningerne. Ved hj\u00e6lp af et caching-plugin er det ofte tilstr\u00e6kkeligt med en mindre webhotelpakke, hvilket ikke n\u00f8dvendigvis giver den bedste ydelse. Denne svaghed kan dog kompenseres p\u00e5 bedste vis.<\/p>\n<p>En anden fordel er, at serveren bedre kan klare et eventuelt rykind af bes\u00f8gende. Det er ikke ualmindeligt, at servere g\u00e5r ned, hvis trafikken stiger, og mange brugere kalder webstedsindholdet p\u00e5 samme tid.<\/p>\n<p>Ulemper<\/p>\n<p>Den st\u00f8rste ulempe ved disse plugins er faktisk indlysende. Det, der er en fordel med hensyn til indl\u00e6sningstid, er samtidig en ulempe med hensyn til webstedets aktualitet. Da siderne med aktiveret plugin er statiske, er det ikke l\u00e6ngere muligt at vise dynamisk indhold. Dette kan nogle gange give problemer, n\u00e5r du bruger andre WordPress-plugins. Det viste websted indeholder data, der blev lagret i cache p\u00e5 et bestemt tidspunkt. De er derfor under visse omst\u00e6ndigheder ganske enkelt for\u00e6ldede.<\/p>\n<p>En anden ulempe er administrationen af s\u00e5danne plugins. Det er ikke ualmindeligt, at caching-plugins er v\u00e6rt for et uendeligt antal funktioner, som den normale WordPress-bruger ikke kender. Ofte handler det om at deaktivere plugin'et, og s\u00e5 begynder problemerne forfra.<\/p>\n<p>Anbefaling: W3 Total Cache<\/p>\n<p>W3 Total Cache Plugin er en klar anbefaling, fordi det kommer med mange nyttige funktioner. Denne faktor er ikke negativ med W3 Total Cache Plugin, fordi de enkelte funktioner er forklaret forst\u00e5eligt, og backend er n\u00e6sten intuitiv at bruge. Derudover er der ogs\u00e5 en detaljeret onlinehj\u00e6lp, som opklarer eventuelle uklarheder.<\/p>\n<p>Mens andre caching-plugins kun giver mulighed for at cache webstedet, er W3 Total Cache fyldt med langt flere funktioner. Den er god til uerfarne brugere og til eksperter, der \u00f8nsker at finjustere deres blog.<\/p>","protected":false},"excerpt":{"rendered":"<p>Sogenannte Caching-Plugins erfreuen sich unter WordPress-Bloggern steht&#8217;s wachsender Beliebtheit.
