Bug ID: 1414473
Summary: Eclipse-PyDev runs pylint at normal priority, eating
up all CPU resources
Product: Fedora
Version: 25
Component: eclipse-pydev
Assignee: akurtako(a)redhat.com
Reporter: rhbz(a)genodeftest.de
QA Contact: extras-qa(a)fedoraproject.org
CC: akurtako(a)redhat.com,
eclipse-sig(a)lists.fedoraproject.org,
jjohnstn(a)redhat.com
Version-Release number of selected component (if applicable):
eclipse-pydev-5.4.0-1.fc25.x86_64
How reproducible:
on every restart of eclipse which causes pylint to run on all python files of
opened projects
Steps to Reproduce:
1. restart eclipse with python projects opened
2. watch system load, processes CPU usage, CPU and IO priority
Actual results:
Eclipse starts a bunch of pylint / python processes, each of them running at
normal CPU and IO priority. If there are enough of them, the computer will
start lagging.
Expected results:
Run background workers at lower priority, preferably both CPU and IO priority.
Additional info:
Workaround: In Window → Preferences → PyDev → PyLint, reduce "Max simultaneous
processes for PyLint" to a number less than your number of cores. Issue might
still happen, but most of the time the python processes will run on one core
only each.
