XNUMX. Alternative PHP Cache (APC cache)

Alternative PHP Cache (APC Cache) kayan aiki ne na buɗe tushen caching don PHP, ana amfani da shi don cache Opcode (fayil ɗin abu) lambar matsakaiciyar PHP.

Rukunin APC ya kasu kashi 2:

1. tsarin cache
2. Cache bayanan mai amfani

Ana amfani da cache na tsarin ta atomatik:

• Wannan yana nufin cewa APC tana adana sakamakon tattarawar asalin tushen fayil ɗin PHP sannan ta sake kiran tambarin lokaci.
• Idan bai ƙare ba, gudanar da shi tare da cache code.
• Tsohuwar cache shine 3600 (awa daya).

Amma wannan har yanzu yana ɓata lokaci mai yawa na CPU.

Don haka, zaku iya saita cache ɗin tsarin don bazai taɓa ƙarewa a cikin fayil ɗin php.ini ba, kuma saita cache ɗin tsarin ba zai taɓa ƙarewa ba (apc.ttl=0).

Koyaya, yin wannan yana buƙatar sake kunna sabar gidan yanar gizo (misali, apache) bayan canza lambar PHP.

A halin yanzu, gwajin aikin APC gabaɗaya yana nufin ma'ajin wannan Layer;

A zahiri, madadin PHP Cache (APC Cache) kuma ana iya ɗaukarsa azaman tsawaita cache cikin ƙwaƙwalwar ajiya,

Tsawon ma'ajin bayanai ne.

XNUMX. eAccelerator

eAccelerator kyauta ne kuma buɗaɗɗen tushen PHP mai haɓakawa.

• Haɓakawa da caching abun ciki mai ƙarfi, wanda zai iya haɓaka aikin caching na rubutun PHP.
• Don haka, ana iya ajiye rubutun PHP a cikin tsarin da aka haɗa don rage yawan amfanin sabar.
• Hakanan yana haɓaka rubutun don haɓaka aikin aiwatarwa, yana haɓaka ingancin lambar PHP sau 1-10.
• eAccelerator baya goyan bayan PHP5.5 ko kuma daga baya.

Kamar yadda aka fahimta daga rubutun:eAccelerator shine haɓaka haɓakawa a cikin PHP.

XNUMX. XCache

XCache buffer/optimizer ne na bude tushen opcode wanda ke inganta aikin PHP akan sabar.

• Kuna iya guje wa maimaita tsarin tattarawa ta hanyar adana bayanan PHP da aka haɗa a cikin ƙwaƙwalwar da aka raba
• Kuma za ku iya amfani da buffer kai tsaye don haɗa lambar don inganta saurin.
• Yana iya yawanci ƙara ƙimar tsara shafi ta hanyar 2 zuwa 5 kuma ya rage nauyin uwar garken.

A gaskiya,XCache shine haɓaka mai haɓaka PHP.

Na hudu, memcached

Memcached babban aiki ne da aka rarraba tsarin caching abu na ƙwaƙwalwar ajiya:

• Ana amfani dashi a aikace-aikacen gidan yanar gizo masu ƙarfi don rage nauyin bayanai.
• Yana rage adadin bayanan da ake karantawa ta hanyar adana bayanai da abubuwan da ke cikin ƙwaƙwalwar ajiya, ta haka ne ke ba da saurin saurin yanar gizo mai sarrafa bayanai.

Ana iya fahimtar shi daga rubutun: fadada cache na ƙwaƙwalwar ajiya, ƙarin amfani da sabar cluster, galibi ana amfani da shi don rarraba cache.

Ana ɗaukar Memcached a matsayin tsawo na ma'ajin bayanai.

XNUMX. Redis

Redis babban mahimman bayanai ne mai ƙima.

• Fitowar redis ya rama sosai saboda rashin ma'ajiyar maɓalli kamar memcached.
• A wasu lokuta, yana iya haɗa bayanai na alaƙa.
• A yawancin lokuta, Redis galibi ana kwatanta shi da memcached.

Mutane da yawa suna tunanin cewa Redis na iya maye gurbin memcached gaba ɗaya, saboda Redis yana da mafi kyawun nau'ikan bayanai kuma aikin ba ya ƙarƙashin memcached:

• Redis ya ɓoye amma a'a;
• Memcached da redis suna da duka biyun.

Kamar yadda na sani, Sina's Weibo da sauran abubuwan da ke kewaye da su sun dogara da Redis, wanda ake iya gani yana da ƙarfi.

Bambanci tsakanin cache na PHP da tsawo na cache na bayanai

1) PHP cache tsawo:

• eAccelerator, XCache sune kari na cache na PHP.

2) Tsawon cache na Database:

• Redis, memcached, APC cache sune kari na cache na bayanai.

(Yawanci mutane biyu kawai suna buƙatar shigar da ɗaya daga cikinsu, kar ku kasance masu haɗama)

Bayan wasu gwaje-gwajen, an gano cewa cache data cache ya wuce wani ƙofa, kuma aikin APC bai kai na mcached cache ba.

Don haka, lokacin zabar kari na cache, wasu mutane za su zaɓi haɗin xcache + memcached, ko haɗin xcache + redis.

Idan kuskure ya faru lokacin shigar da kari na cache da yawa a lokaci guda, ana ba da shawarar shigar da tsawo na cache ɗaya kawai sannan a cire sauran.

Takaitacciyar kwatancin Kwatancen Mai Saurin PHP

• Ta hanyar gwaji, eAccelerator shine mafi kyawun haɗin lokacin buƙata da amfani da ƙwaƙwalwar ajiya, amma eAccelerator baya goyan bayan PHP 5.5 ko kuma daga baya.
• Ta hanyar gwajin, saurin tare da mai haɓaka yana da sauri sau 3 fiye da ba tare da mai haɓakawa ba.
