Subject: [PATCH 1/6] environment: reduce calls to g_time_zone_new_local()
|
|
|
|
Creating a new GTimeZone for the local timezone can be quite expensive if
|
|
done repeatedly. It requires an open(), mmap(), and parsing of
|
|
/etc/localtime.
|
|
|
|
This patch was provided by Florian, and I've tested it as far back as
|
|
3.28.4 to ensure that we are really reducing the number of open() calls
|
|
on the compositor thread.
