It's nothing to worry about.

Things will often take a while (up to perhaps several seconds) if they
involve DNS lookups.  Doing things with lists provided by Spamhaus etc.
will usually involve DNS lookups.  While it waits for the reponse from
resources like DNS servers over which it has no control, rspamd can get
on with other things so as not to slow down overall mail throughput.

If you look in

.../src/libserver/symcache/symcache_runtime.cxx

you'll see that the message "enable slow timer delay" is just logging
that rspamd is itself doing that because things are taking a while.
The message is not a direction for you to do anything to enable a
"slow timer" in the configuration, nor anything along those lines.

Bear in mind that English is not the rspamd author's first language.
If I'd written such a message in my code, I think I might have used a
phrase such as "enabling long duration timer" or something like that.
