There are some of the early Internet Monthly reports online at 
http://ftp.us.xemacs.org/ftp/pub/internet-monthly-reports/ (incomplete 
before mid-1986)

The April 1986 edition (imr8604.txt) has the following...

   INTERNET ARCHITECTURE .Grab=5;
 
      .IOvr=3;1. A third draft of a document on gateway requirements was
      circulated for advice and comment in INENG, INARC and the Workshop
      on IS-IS Routing held at NBS. Strictly speaking, this is an NSF
      document and is being reviewed both as a service to NBS and as
      possible guidance for the DoD community.
 
      2. An agenda and marching orders are in place for the first
      meeting of INARC to be held at BBN on 8-9 May. Dave Clark has
      agreed to attend, as well as Lyman Chapin, who chairs the ANSI
      committee charged with routing issues. Marianne Gardner and
      possibly others from BBN will summarize their work on advanced
      routing issues.
 
      3. Discussion continues over a proposed RFC on ISO addressing
      co-authored by Hans-Werner Braun and Ross Callon. This is a legacy
      of the now defunct GADS, but may serve as an opening wedge for
      more general Dod-ISO convergence issues. .IOvr=0;

   INTERNET ENGINEERING .Grab=5;
 
      .IOvr=3;1) The initial meeting of this Task Force convened during
      an open afternoon of the final GADS on January 16, 1986.  A
      tentative Task Force agenda of short, mid and long term goals was
      set.
 
      2) The first full meeting was held on April 8-9, 1986 where the
      agenda focused on: .IOvr=0;
 
         - Recent Internet performance degradation
         - EGP Modifications
         - IP refinements in hosts and gateways for improved routing and
           congestion control
 
      3) A summary of recent Internet performance was given: .Grab=8;
 
                                       Dec 85     Jan 85
      Traffic Sent by Mail Bridges     ~27        ~35   (Mpackets/week)
      Traffic Sent by Mail Bridges     ~90        ~105  (Mpackets/week)
 
      Traffic Dropped by Mail Bridges  ~3%        ~6%
      Traffic Dropped by Mail Bridges  ~2%        ~4%
 
      .IOvr=3;4) BBN discussed two possible sources for these sharp
      changes: 1) a bug in the LSI gateway routing software, which was
      recently discovered and corrected and 2) resource shortage in the
      Mail Bridge PSNs, due to be alleviated by end of April).
 
      6) EGP modifications of two types were discussed: 1) areas in
      which the specification needed to be tightened and 2) areas in
      which the specification can profitable be `re-interpreted'.
      Examples of the second type include fragmented updates and
      interpreting the metric (eg, RFC975 - Autonomous Confederations).
 
      7) Several new ICMP messages were proposed to facilitate fault
      isolation and routing (eg, initial gateway discovery, discovery of
      preferred address for multi-homed hosts).  A co-operative
      congestion control scheme was proposed. Discussion of this scheme
      will continue in the Internet Architecture Task Force. .IOvr=0;
 
      8) Actions in progress:
 
         - continued tracking of Internet traffic for expected
           improvements,
         - produce RFC of EGP modifications,
         - produce RFC specifying host attachment and IP/ICMP
           modifications.
 
      .IOvr=3;9) Detailed meeting notes are available upon request to
      [e-mail], with cc to [e-mail].  Those requesting
      the notes will be added to the Task Force interest list. .IOvr=0;

BTW, I came across this mail message from the ancient history of the tcp_ip mailing list (archived at UCL http://www-mice.cs.ucl.ac.uk/multimedia/misc/)
I liked the last paragraph...

The examples you cite of "horrible" EGP routing are probably due to the
extra-hop problem in the core.  Apparently we have not done an adequate
job of information-spreading, if you are not aware of this problem.  I
seem to recall a blaze of messages on this very subject within the past 6
months, probably on the tcp-ip list.  It began with a complaint almost
identical to yours, and ended with a scholarly explanation of the
extra-hop problem by Dave Mills.

The extra-hop problem can at worst double the core traffic, and it is
scheduled to go away when the Butterflies take over the core.  I forget
the exact predicted date from BBN, but rescue is in sight.

As for performance, in some funny sense EGP is (deliberately) designed for
poor performance, in the sense that it is intended to server as a firewall
against misbehaviour by routing domains outside the core.  It is true, as
Mike StJohns says, that EGP is not a routing protocol; it is also true that
this fact has led to serious restrictions in topology and therefore a
crash effort is being mounted to replace EGP with a routing protocol, under
the direction of the INENG and INARCH task forces. 
 
However, maybe we are asking too much of EGP.  Perhaps we are trying to
make it a technical fix for administrative problems.  To avoid bad things
like oscillations and routing loops in the face of the "diversity" (to
use a nice word) of the Internet as a whole, EGP or whatever replaces it
will always have to use long time constants and provide some sub-optimal
routes.  At the present time, the Internet is growing largely by
accretion of new Autonomous Systems, and this must lead to some 
degradation as you cross boundaries.  If we want better overall
performance, we need to persuade these systems to aggregate into bigger
systems, each run by centralized and professional Internet management,
and each using a carefully-optimized IGP.

I go into all this polemic, because lately I have been exposed to an 
awful lot of technological optimism (ask NASA about that!) about 
Internetting.  I wish we could convince some of the new players in the
Internet game that it takes great technical sophistication and wisdom
to make this stuff work well.  The Anarchy Model of Internetting,
while theoretically feasible due to EGP, is not really a very wise way
to go.
