Spustili jste kampa\u0148, odeslali newsletter, sd\u00edleli p\u0159\u00edsp\u011bvek na s\u00edt\u00edch, nebo se v\u00e1m prost\u011b za\u010dalo da\u0159it ve vyhled\u00e1v\u00e1n\u00ed.

Pr\u00e1zdn\u00e1 str\u00e1nka, obr\u00e1zky, co se loudaj\u00ed, \u010dek\u00e1n\u00ed, kter\u00e9 jako by nem\u011blo konec.<\/p>\n\n\n\n

Nezoufejte. V\u011bt\u0161inu p\u0159\u00ed\u010din zpomalen\u00ed odhal\u00edte sami b\u011bhem p\u00e1r minut. V tomhle n\u00e1vodu v\u00e1s krok za krokem provedeme t\u00edm, co si ov\u011b\u0159it jako prvn\u00ed. Bu\u010f na p\u0159\u00ed\u010dinu p\u0159ijdete rovnou, nebo budete p\u0159esn\u011b v\u011bd\u011bt, co se d\u011bje, a p\u0159ed\u00e1te n\u00e1m to tak, a\u0165 to vy\u0159e\u0161\u00edme co nejrychleji.<\/p>\n\n\n\n\n\n\n\n

Pro\u010d se t\u00edm v\u016fbec zab\u00fdvat<\/h2>\n\n\n\n

Pomal\u00fd web nen\u00ed jen technick\u00e1 drobnost. Je to v\u00e1\u0161 obchod. Ka\u017ed\u00e1 sekunda nav\u00edc rozhoduje o tom, jestli n\u00e1v\u0161t\u011bvn\u00edk nakoup\u00ed, ode\u0161le popt\u00e1vku, do\u010dte \u010dl\u00e1nek, nebo odejde ke konkurenci.<\/p>\n\n\n\n

\u010c\u00edsla to potvrzuj\u00ed. Podle v\u00fdzkumu Google a SOASTA se p\u0159i zpomalen\u00ed na\u010dten\u00ed mobiln\u00ed str\u00e1nky z 1 na 10 sekund zvy\u0161uje pravd\u011bpodobnost, \u017ee n\u00e1v\u0161t\u011bvn\u00edk odejde, o 123 %. Va\u0161i n\u00e1v\u0161t\u011bvn\u00edci prost\u011b ne\u010dekaj\u00ed. A co je hor\u0161\u00ed, pomalost si \u010dasto nespoj\u00ed s do\u010dasn\u00fdm v\u00fdpadkem, ale s va\u0161\u00ed zna\u010dkou. Web je dnes v\u011bt\u0161inou prvn\u00ed kontakt s va\u0161\u00ed firmou. Kdy\u017e se vle\u010de, p\u016fsob\u00ed pomale i cel\u00e1 firma.<\/p>\n\n\n\n

Co zrovna te\u010f za\u017e\u00edvaj\u00ed va\u0161i n\u00e1v\u0161t\u011bvn\u00edci<\/h2>\n\n\n\n

Zkuste se na chv\u00edli pod\u00edvat o\u010dima \u010dlov\u011bka, kter\u00fd na v\u00e1\u0161 web pr\u00e1v\u011b p\u0159i\u0161el. Ne\u0159e\u0161\u00ed datab\u00e1zi, \u0161ablonu ani cache. Klikne a \u010dek\u00e1. A kdy\u017e se nic ned\u011bje, za\u010dne pochybovat: Je to tady bezpe\u010dn\u00e9? Projde objedn\u00e1vka? Nezaplat\u00edm dvakr\u00e1t? M\u00e1 smysl tu v\u016fbec z\u016fst\u00e1vat?<\/p>\n\n\n\n

U e-shopu to znamen\u00e1 opu\u0161t\u011bn\u00fd ko\u0161\u00edk, u firemn\u00edho webu ztracenou popt\u00e1vku, u magaz\u00ednu ni\u017e\u0161\u00ed \u010dtenost. Pr\u00e1v\u011b proto se vyplat\u00ed jednat rychle. A dobr\u00e1 zpr\u00e1va zn\u00ed: prvn\u00ed kroky zvl\u00e1dnete sami.<\/p>\n\n\n\n

Projd\u011bte si to krok za krokem<\/h2>\n\n\n\n

Ne\u017e za\u010dnete ladit detaily, dva odkazy v\u00e1m nejrychleji \u0159eknou, jestli je n\u011bco v nepo\u0159\u00e1dku na na\u0161\u00ed stran\u011b: diagnostika webhostingu<\/a> uk\u00e1\u017ee stav va\u0161ich slu\u017eeb a Status<\/a> p\u0159\u00edpadn\u00fd v\u00fdpadek infrastruktury. Kdy\u017e je tam v\u0161echno v po\u0159\u00e1dku, p\u0159\u00ed\u010dina bude nejsp\u00ed\u0161 v aplikaci a pom\u016f\u017eou v\u00e1m kroky n\u00ed\u017ee.<\/p>\n\n\n\n

    \n
  1. Zjist\u011bte, jestli je web pomal\u00fd pro v\u0161echny, nebo jen pro v\u00e1s.<\/strong> Otev\u0159ete ho na mobiln\u00edch datech, v anonymn\u00edm okn\u011b, na jin\u00e9m za\u0159\u00edzen\u00ed a z jin\u00e9 s\u00edt\u011b. Kdy\u017e se vle\u010de jen u v\u00e1s, probl\u00e9m b\u00fdv\u00e1 lok\u00e1ln\u00ed: p\u0159et\u00ed\u017een\u00e1 wifi, prohl\u00ed\u017ee\u010d nebo star\u00e1 DNS cache. To d\u00e1te do po\u0159\u00e1dku hned a bez ciz\u00ed pomoci.<\/li>\n\n\n\n
  2. Ov\u011b\u0159te, jestli zlob\u00ed cel\u00fd web, nebo jen jeho \u010d\u00e1st.<\/strong> Projd\u011bte zvl\u00e1\u0161\u0165 \u00favodn\u00ed str\u00e1nku, ko\u0161\u00edk, vyhled\u00e1v\u00e1n\u00ed a administraci.

  3. Vzpome\u0148te si, co jste naposledy m\u011bnili.<\/strong> Aktualizovali jste syst\u00e9m nebo plugin? P\u0159idali novou \u0161ablonu, m\u011b\u0159ic\u00ed k\u00f3d, reklamn\u00ed skript nebo chat? Importovali data?

Otev\u0159ete si analytiku. N\u00e1hl\u00e1 \u0161pi\u010dka se chov\u00e1 jinak ne\u017e trval\u00e9 zpomalen\u00ed. Kdy\u017e je p\u0159id\u011blen\u00fd v\u00fdkon vy\u010derpan\u00fd, web to \u010dasto ohl\u00e1s\u00ed chybou 503<\/a>.<\/li>\n\n\n\n
  5. Zkontrolujte z\u00e1klad.<\/strong> Velikost str\u00e1nky a obr\u00e1zk\u016f, jestli funguje cache, stav datab\u00e1ze a chybov\u00e9 logy.

  6. Prov\u011b\u0159te extern\u00ed slu\u017eby.<\/strong> Platebn\u00ed br\u00e1na, chatovac\u00ed widget, analytika nebo reklama um\u00ed zdr\u017eet cel\u00e9 na\u010dten\u00ed, i kdy\u017e v\u00e1\u0161 web b\u011b\u017e\u00ed v po\u0159\u00e1dku.
