RHEL 7.3\u2019\u00fcn \u00e7\u0131kmas\u0131yla birlikte bu pop\u00fclerlik iyice artaca\u011fa benziyor. Bu yeni \u00f6zelliklere \u015f\u00f6yle bir g\u00f6z atacak olursak:<\/span><\/p>\n

Performans<\/span><\/strong><\/p>\n

RHEL 7.3 daha h\u0131zl\u0131 a\u011f ve daha hafif t\u00fcnel ihtiyac\u0131na kar\u015f\u0131l\u0131k veriyor. Bu \u00f6zellikler RHEL 7.3\u2019\u00fcn daha g\u00fcvenli, rand\u0131manl\u0131, \u00f6l\u00e7eklendirilebilir ve esnek olmas\u0131n\u0131 sa\u011fl\u0131yor.

Ayn\u0131 zamanda, veritabanlar\u0131, olay i\u015flemeleri ve sanal makineler gibi y\u00fcksek i\u015flemli uygulamalar y\u00fcksek girdi-\u00e7\u0131kt\u0131 (IO) oranlar\u0131na ve d\u00fc\u015f\u00fck gecikme oranlar\u0131na ihtiya\u00e7 duyar. Kal\u0131c\u0131 bellek gibi yeni donan\u0131m teknolojileri bu sorunu ele al\u0131yor ve RHEL 7.3 de bu yeni nesil bellek cihazlar\u0131n\u0131 destekliyor. Buna ek olarak, RHEL 7.3 Block SCSI taslak format\u0131 ve Flex Files taslak format\u0131 vas\u0131tas\u0131yla, performansa duyarl\u0131 Paralel NFS (pNFS) y\u0131\u011f\u0131nlar\u0131n\u0131n y\u00f6netimini kolayla\u015ft\u0131r\u0131yor.<\/span><\/p>\n
