Description Paul Wouters 2017-02-20 11:47:58 EST

Description of problem:

As per Christian Heimes <cheimes@redhat.com>:

while I was investigating performance issues in FreeIPA, I noticed that
both F25 and RHEL come with an older version of python-idna. That
version has a serious performance issue. It takes round about 100ms to
import the idna package. Import increases RAM consumption of the process
(RSS) by about 20 MB.

https://github.com/pyca/cryptography/issues/3409#issuecomment-281095501

It affects IPA framework, IPA command line, Custodia, and any other
application that import python-cryptography. Right now we are wasting 60
MB (2x20 MB for IPA WSGI processes, 1x20 MB for Custodia). For FreeIPA
4.5 I'm planning to bump up the WSGI daemon processes from 2 to 5.

Is it still possible to request a RHEL rebase of python-idna?

Christian

Comment 3 Abhijeet Kasurde 2017-05-25 08:07:06 EDT

Verified using IPA and Python-idna version ::

# rpm -qa ipa-server python-idna
ipa-server-4.5.0-13.el7.x86_64
python-idna-2.4-1.el7.noarch

Marking BZ as verified.
