Seniau rašiau, kad teko išmesti eAccelerator’ių dėl pastebėtų negerų dalykų.

Pasirodžius Release Candidate 1 versijai nusprendžiau vėl jį išbandyti ir pažiūrėti, ar man ramybės nedavę bug’ai yra ištaisyti.

Atrodo, kad viskas veikia nepriekaištingai. Jau praėjo kelios dienos ir nei vienas apache thread’as nesicrash’ino ar pan. Nemanau, kad atsiras kažkokia tai didesnė problema :)

O dabar palyginimui, ką duoda eAccelerator:

Seniau rašiau apie framework’o evoliucija ir irgi leidau ab testus. Pažiūrėkime, kokie buvo rezultatai visiškai to pačio kodo be eAccelerator:

Skirtumas, manau, yra labai akivaizdus.Vos ne 50% (~45%) efektyviau. Jėgelė :)

O čia šiaip control panel’ės shoot’as:
