Apache versus nginx (versus lighttpd ) part 2

In postul anterior faceam o comparatie intre apache si nginx. Am luat de data aceasta in calcul si lighttpd. Am reluat testele pe o masina medie ( o masina care dupa parerea mea ar putea sa fie folosita pentru proiecte de dimensiuni mici/medii ). Rezultatele testelor:

Dupa cum se poate observa testul cu autobench nu au dat rezultate concludente. E timpul pentru alt model de teste si refacute testele.

Intra in scena ab-ul:

Distributie linux: TFM linux server 32. Pentru toate testele am folosit un fisier html de lungime 7638 bytes. Concurency level pentru teste a fost 500 iar numarul total de cereri a fost 50000.

Dupa cum se poate observa per ansamblu nginx s-a comportat cel mai bine, a avut cele mai multe requesturi servite pe secunda. Pe locul doi lighttpd la diferenta foarte mica de nginx. Ultimul clasat s-a dovedit apache-ul la viteza de servire.

Concluzia e simpla. Pentru fisiere statice utilizati lighttpd sau nginx. Alegerea intre ele se face evident functie de caz si in functie de preferinte. Noi nu am pus nginx pe serverele de trafic foarte foarte mare preferind lighttpd-ul. Desigur in tfm gasiti toate cele 3 web servere si il puteti folosi cel care va place mai mult.
