It may not be clear from the first few lines  of  my  "gename.c",
but  if your system is not "ITTVAX" and you just compile gename.c
without -DTSSEQ -DSEQHUNK=10,  you  will  get  exactly  the  same
behavior  as the original.  This was perhaps a bit of overcaution
on my part to make the old behavior the default.  If you just use 
the -DTSSEQ flag, you will get  base  62  sequence  numbers,  but
(alas) still fetch them from the sequence file 1 at a time.  

An easy way to tell if the -DTSSEQ flag was in effect is:

	nm -g uux | grep _tstoa

If the -DTSSEQ option is not defined, "tstoa()" is not  compiled,
in  which  case  you  can  be  sure the chunking option is not in
effect.  If the symbol is present, do: 

	cat /usr/lib/uucp/SEQF
	uux foobaz!mumblefratz
	cat /usr/lib/uucp/SEQF

which although uux will complain about  unknown  system  "foobaz"
will  still  force  a  "gename"  call  or  two.  By comparing the
sequence file before and after you can tell what the  chunk  size
is (NOTE: a normal uux call will generate ~6 "gename" calls).  

This is a rather long prelude to the totally unrelated conclusion 
that this is still not your problem, as uuxqt won't call "gename" 
unless an output file is specified; uurec doesn't call it at all; 
and uucico won't call it unless the "callback"  flag  is  set  in
L.sys  (or  USERFILE,  I forget which; for long and gory reasons,
the callback feature just plain doesn't work anyway).  

Conclusion:  if  the  "uurec"  operation  takes  too  long,  look
elsewhere  than the UUCP system for the culprit.  Previously Mark
Horton (I think) has mentioned that if your news history file  is
large,  inserting  a new article will take a long time.  Versions
2.8 (I think)  and  later  of  "expire"  would  correctly  expire
articles  and  re-write  the  history  file to contain only those
articles left in the system.  

I am not familiar with the uurec operation, so I really can't
comment further.
