Yes, across NFS. I copied the file to a local drive and ran both mutts. The
time was about the same (1.8 sec). Both mutts were also run from a local
drive.
My system is an Ultra 60 with two 450MHz processors. Network is 10BT
(dedicated through an ethernet switch to ATM backbone). OS is Solaris 2.6 with
relatively up-to-date patches.

The file normally resides in my home directory which is NFS mounted from an
Auspex. Relevant output from nfsstat -m
/home/ax10 from brtpyc9d:/home/ax10
Flags:
vers=3,proto=udp,sec=sys,hard,intr,link,symlink,rsize=32768,wsize=32768,retrans=5

All: srtt=8 (20ms), dev=4 (20ms), cur=3 (60ms)
brtpyc9d is an interface on the same subnet as my workstation.
I've attached mutt -v output. They are essentially the same except for options
added or removed between the two releases.

Interestingly enough, I rebuilt both under HP-UX 10.20 and I got similar times
to bring up the same file (across NFS) with both versions (about 20 sec). I've
attached the mutt -v output for both versions under HP-UX 10.20.
I went back and rebuilt both versions under Solaris 2.6. I still get the same
reults -- 7.9 secs for mutt 1.0, 29-30 secs for mutt 1.1.9.
I'm open to other suggestions/explanations.
