[Mailman-Users] running External Archiver on background/foreground

[Mohamed CHAARI]

Hi all,

I'm using Mailman for lists management, in a collaboration 
infrastructure site.
I configured Mailman so that an external archiver is used, but I 
hesitate to run this archiver in background or foreground.

More concretely, in mm_cfg.py conf file, should I put:

PUBLIC_EXTERNAL_ARCHIVER = 'cat > /var/run/mailman/mail_tmp; 
/usr/local/bin/external_arch %(listname)s'

or

PUBLIC_EXTERNAL_ARCHIVER = 'cat > /var/run/mailman/mail_tmp; 
/usr/local/bin/external_arch %(listname)s &'

What do you recommend ? is there a difference, in terms of performance ?
Is there a risk of system overload, for one of the 2 solutions, when 
dealing with too big archives ? (I have some archives exceeding 50 M)

Thank you
