I have found that if you increase the "packet" size to 32K IND$FILE
will improve greatly. The only issue I have run across with doing this
is that some emulators have predefined settings (2, 4, 8, 16 and 32K)
and CICS can't suport 32K so you must specify 16K, which improves
performance over the default of 2K, but still not as good as 32K.
We have found that over typical WAN links going to 16K or larger
improves IND$FILE to just about equal of FTP and we don't have to
re-write our applications or define OMVS segments for all of our users.

IND$FILE seems clumsy to me and seems to work
differently depending on whether you invoke it
from the READY prompt or from ISPF Option 6.
Setting the options to get the results desired is
also a bit of a crap shoot.
I don't know why using a URL instead of a numeric
IP address would be a problem; it should only have
to resolve a URL once per connection. (Surely they
don't do it inside the loop instead of outside?)
The only time I use IND$FILE is if my customer
won't define an OMVS segment for my userid.
I'm with Ted on this. Given a choice,
I'll use Seagull's FTP every time.

I know I'm late catching up on this discussion, but I just wanted to add a
little tidbit. Using Personal Communications, and sometimes using
IND$FILE instead of FTP I was finding that IND$FILE uploads were going
very slowly for me. A friend showed me that changing my link parameters
configuration to use the numeric dotted IP address of the host instead of
the host name would speed up my uploads. It did speed them up very
noticeably. It sped it up so much that instead of using FTP all the time
and avoiding the IND$FILE used by PCOMM, I now use the IND$FILE upload for
all but the very biggest files just because of the convenience of having
the button right there and the templates I have defined for files.
