# Which Problems Are Solved
Comparing the v3 and v4 deployments we noticed an increase in memory
usage. A first analysis revealed that it might be related to the
(multiple) initialization of the `i18n.Translator`, partially related
# How the Problems Are Solved
Initialize the tranlator once (apart from the translator interceptor,
which uses context / request specific information) and pass it to all
necessary middleware.
# Additional Changes
Removed unnecessary error return parameter from the translator
initialization.
# Additional Context
- noticed internally
- backport to v4.x
