If I create specific transport like slow and high
Slow_connection_cache_time_limit = 2s
High_connection_cache_time_limit = 5s

I have to add the value in scache(8) and smtp(8)?

==========================================================
Used in         Parameter name and default value
==========================================================
scache(8)       connection_cache_ttl_limit = 2s
scache(8)       connection_cache_status_update_time = 600s

smtp(8)         smtp_connection_cache_destinations =
smtp(8)         smtp_connection_cache_on_demand = yes
smtp(8)         smtp_connection_cache_time_limit = 2s
smtp(8)         smtp_connection_reuse_time_limit = 300s

On this mailing list we type reply text BELOW the replied-to
text, which is shortened to just provide the necessary context.

Support for Postfix covers only features that can be configured in
main.cf and master.cf. As documented in CONNECTION_CACHE_README,
the connection reuse parameters and default values are:

==========================================================
Used in         Parameter name and default value
==========================================================
scache(8)       connection_cache_ttl_limit = 2s
scache(8)       connection_cache_status_update_time = 600s

smtp(8)         smtp_connection_cache_destinations =
smtp(8)         smtp_connection_cache_on_demand = yes
smtp(8)         smtp_connection_cache_time_limit = 2s
smtp(8)         smtp_connection_reuse_time_limit = 300s
==========================================================

If you set any of these parameters in master.cf, they must be set
with the daemon program that uses the parameter, otherwise the
parameter setting will have no effect.

There is no support for source-code changes.
