Thanks.

Code:
pause=0
user=1

(for (( ; ; ))
do
   speed=`cat speed.log`
   if [ "$speed" -lt 10 ]; then
      pause=1
   else
      pause=0
   fi
sleep 30
done) &

function user () {
   local user=$1   
   while [[ "$pause" = 1 ]; do
      echo pausing script
      sleep 10
   done
   # else continue
}

for (( user = 1; user <= $users; user++ )); do
  one_user $user &
done

Correct it

while [ "$pause" -eq 1 ]; do

--edit---

I didn't understand what's your aim ? where you are breaking loop ?

tracker-status

tracker-status(1)						   User Commands						 tracker-status(1)

NAME

       tracker-status - Report the state of all data miners

SYNOPSIS

       tracker-status [OPTION...]

DESCRIPTION

       tracker-status  shows  the status of all miners installed. It also allows pausing and resuming of miners. For tracker-store state, you need
       to use tracker-control

OPTIONS

       -?, --help
	      Show summary of options.

       -f, --follow
	      Follow status changes as they happen. This requires Ctrl+C to stop and return to the command line. Each new status is put on  a  new
	      line. To get more information, you can use --detailed with this.

       -d, --detailed
	      For the most part, this purely provides a timestamp with each status update to follow WHEN changes happened.

       -s, --list-common-statuses
	      This  will  list statuses most commonly produced by miners and the store. These statuses are not translated when sent over D-Bus and
	      should be translated by each application. These are not considered static and are subject to change at any point.

	      Additionally, these statuses are not the only ones which may be reported by a miner. There may be other  states  pertaining  to  the
	      specific roles of the miner in question.

       -l, --list-miners-running
	      This  will  list	all miners which have responded to a D-Bus call.  Sometimes it is helpfult to use this command with --list-miners-
	      available.

       -a, --list-miners-available
	      This will list all miners which are available even if they are not running at the moment.

       -i, --pause-details
	      For listing all miners which are paused and the reasons for being paused, you can use this. It will  also  display  the  application
	      that requested the pause too.

       -m, --miner=MINER
	      This  argument  is  used	with --pause and --resume to say which miner you want to pause or resume. You can use the full D-Bus name,
	      e.g.  org.freedesktop.Tracker1.Miner.Files OR you can use the suffix, e.g.  Files

       -p, --pause=REASON
	      The REASON here is useful to know WHY the miner should be paused. A miner can be paused many times by  multiple  applications.  Only
	      when  all  pauses  have  been resumed will it continue. If successful, a cookie will be given to uniquely identify the request. This
	      cookie is used to resume the pause at a later stage.

       -r, --resume=COOKIE
	      The COOKIE is given by a successful --pause command. It is a number which identifies each pause request. When all pauses	have  been
	      resumed, the miner will resume working.

       -V, --version
	      Print version.
