--- Comment #17 from Jaime Torres <jtam...@gmail.com> --- Git commit 8d73867b3d4339ec026f92c4c2e89c265249aeb2 by Jaime Torres. Committed on 07/02/2018 at 18:05. Pushed by jtamate into branch 'master'. Don't stat(/etc/localtime) between read() and write() copying files Summary: Unfortunately, QDateTime::currentDateTime() checks /etc/localtime each time it is called. Chaning to QElapsedTime, no check of /etc/localtime. Reproducing bug 384561, the strace of file.so was something like: read(), stat(/etc/localtime), stat(/etc/localtime), stat(/etc/localtime), stat(/etc/localtime), stat(/etc/localtime), write(), read() ...... Now it is: read(), write() It also reduces the cpu in io/wait around 10% in a debug build. Test Plan: kio tests work as before desktop: works in dolphin Reviewers: #frameworks, fvogt, dfaure Reviewed By: dfaure Subscribers: fvogt, ngraham Tags: #frameworks Differential Revision: https://phabricator.kde.org/D9983 M +14 -13 src/core/slavebase.cpp https://commits.kde.org/kio/8d73867b3d4339ec026f92c4c2e89c265249aeb2 -- You are receiving this mail because: You are watching all bug changes.
