Viskas prasidėjo labai labai seniai… Kai music.lt buvo perrašomas iš pagrindų. Reikėjo framework’o. Jis atsirado. Tobulėjo… Išsiplėtė… Tada jis tapo ir www.erdves.info pagrindu.

Visoje šioje istorijoje taip pat rastume kokius 4 radikalius framework’o perrašymus…
Galų galiausiai teko atsisveikinti su PHP4 ir pereiti prie PHP5… Viskas tiesiog tobulėjo :) Ir dabar yra tai, kuo aš džiaugiuosi! :)

Bet, manau, viską reiktų pagrįsti faktiškai… Taigi leidžiame apachebench ir žiūrime:

1. Pirmiausiai bandysime www.erdves.info. Čia panaudota gan sena framework’o versija (praktiškai ta pati sukasi ir ant dabartinio music.lt). Manau, kad ~ metų senumo.. O gal senesnė. Kodas 2x trumpesnis nei dabar, sisteminių modulių irgi mažiau. Mažiau dinamiškumo, OOP yra PHP4 stiliaus. Pažiūrėkime:

2. Dabar bandome savaitės senumo kodinę bazę. Sistema gan stipriai išplėsta: nauji moduliai, daugiau dinamiškumo ir automatizacijos. Gan nemažai PHP5 OOP kodo, tad suderinamumo su PHP4 nebėr. Žiūrime:

3. O dabar panaudojam overloading’ą… :) Sisteminiai moduliai loadinami tik tada ir tik tada, kai jie yra reikalingi (t.y. yra bandomi panaudoti). Žinoma, kažką panašaus galima buvo padaryti su PHP4 ir papildomomis funkcijomis, bet tada būtų buvę mažiau patogumo, nes sisteminių modulių kūrimo realiai nebuvo galima automatizuoti. Paleidžiam:

Hmm… Manau, rezultatai viską pasako :) Dar reiktų paminėti ir tai, kad viskas sukasi ant paprasto kelių metų kompiuterio, kurio parametrai yra tokie: Hardware: AMD Duron 900MHz, seni geri 512MB RAM, kurių nelabai ir užtenka paleidinėjant ab. Software: FreeBSD6, PHP5.1.4, Apache 2.0.55. Seniau buvo naudojamas eAccelerator, bet šiuo metu jis yra nebenaudojamas dėl crash’ų.

4. Palyginimui wordpress ir www.zlotkus.com rezultatai:

Wordpress yra tikrai kažkoks griozdas… Funkcionalumo jame tikrai nėra tiek daug… Lieka tik viena išvada – Wordpress’o kodas yra tikrai prastas :) Ateityje planuoju programuoti weblog’o modulį savo framework’ui. Funkcionalumu jis bus praktiškai toks pat kaip ir Wordpress… O greičio rezultatus tada ir pamatysim :)

Pabaigai…

Rezultatai tikrai nuostabūs. Greitis padidėjo 3,2 karto! :) Artimiausiu metu atnaujinsiu music.lt iki naujausios framework’o versijos… Įdomu, kiek tada jis dar pagreitės? Dabar puslapio sugeneravimas užtrunka vidutiniškai ~60ms. Gal bus 20ms? :) Sunkiai tikėtina… Bet, manau, 30-40ms tikrai pasieksiu :)
