Optimizing the Shell Script [Expert Advise Needed]

I have prepared a shell script to find the duplicates based on the part of filename and retain latest.

Code:

    #!/bin/bash
    if [ ! -d dup ]; then
        mkdir -p dup
    fi
    NOW=$(date +"%F-%H:%M:%S")
    LOGFILE="purge_duplicate_log-$NOW.log"
    LOGTIME=`date "+%Y-%m-%d %H:%M:%S"`
    echo "$LOGFILE"
    echo "Started at $LOGTIME " >> $LOGFILE
    echo "Before File Count " >> $LOGFILE
    cd /tmp/sathish/GB/
    ls -l | wc -l >> $LOGFILE
    for i in `find /tmp/sathish/GB/ -type f \( -iname "*.xml" \) -printf '%T@ %p\n' | sort -rg | sed -r 's/[^ ]* //' | awk 'BEGIN{FS="_"}{if (++dup[$1] >= 2) print}'`;
    do
    if [! -z $i]; then
    echo "No Duplicates Identified" >>$LOGFILE
    fi
    echo "$i $dup">>$LOGFILE
    mv -v $i dup;
    done
    echo "Ended at $LOGTIME " >> $LOGFILE
    echo "After File Count " >> $LOGFILE
    cd /tmp/sathish/GB/
    ls -l | wc -l >> $LOGFILE

I recently tested this script in test server.

Code:

    Time Taken	22 Min
    Before File Count	227874
    After File Count	58137
    Duplicates Moved to Dup folder	169737

I am unable to implement this production server as it consumes more cpu, any way to optimize this query.

Truly appreciate your expertise advise to minimize the cpu during this process.

Suggestions most welcome
