FWIW, I've found the opposite to be true. Splitting up larger files and
reducing the depth of the hierarchy marginally improves agenda
performance (~ 0.2 seconds acc. to elp). But in my case, I split 10
files into 40, so I have no idea what 200 files would do. Perhaps
there's a sweet spot somewhere? I also haven't used mobile org.

In my experience, archiving old items and reducing the number of active
todos is the best way to keep the agenda snappy.

Perl is always handy for this type of thing:

--8<---------------cut here---------------start------------->8---
#!/usr/bin/perl
use strict;
use warnings;

my $mergefile = "/tmp/merged.org";

open NEWFILE, ">", $mergefile 
  or die "Can't open $mergefile: $!";

while (<>) {
  s/^(\*+)/*$1/;
  s/^#\+TITLE:\s+(.*)$/* $1/;
  s/^(#\+\w+:.*)$/: $1/;
  print NEWFILE "$_";
}

close NEWFILE;
--8<---------------cut here---------------end--------------->8---

Note: This is a quick proof of concept. Use at your own risk. ;)

Best,
Matt
