Well I am not a DNS expert but why Google have the primary gmail MX record
without load balancing and all secondaries are sharing the same priority
level.

I have a server that relay usenet messages to my gmail account and here is a
week worth of stats showing how google mail servers are handling incoming
mails:

Total Number of messages sent to gmail: 1945 messages of which:

1888 (97%) messages were gated through Gmail's Primary mail server
(gmail-smtp-in.l.google.com).
21 messages were gated through Gmails Secondary (gsmtp171.google.com)
13 messages were gated through Gmail's Secondary (gsmtp171-2.google.com)
10 messages were gated through Gmail's Secondary (gsmtp185-2.google.com).

So in short, 97% of the email was delivered through the primary while the
secondaries only served 3%.

My question why they do not make all mail servers at the same priority level
instead of current
which load balance the Secondaries only.

BTW mx records for google gmail are:

MX 5 gmail-smtp-in.l.google.com.
MX 10 gsmtp171.google.com.
MX 10 gsmtp185.google.com.
MX 10 gsmtp171-2.google.com.
MX 10 gsmtp185-2.google.com.
MX 20 gsmtp57.google.com.

each have 1 minute TTL.
