Bash script / while loop arquivo de leitura extremamente lento

Eu tenho um loop while que lê um arquivo de log ftp e o coloca em uma matriz, para que eu possa pesquisar na matriz e corresponder / procurar um fluxo. Infelizmente, o loop while está demorando uma eternidade para passar pelo arquivo, é um arquivo muito grande, mas deve haver outra maneira mais rápida de fazer isso.

# read file into array for original search results
while read FTP_SEARCH
do
ogl_date[count]=`echo $FTP_SEARCH | awk '{print $1, $2}'`
ogl_time[count]=`echo $FTP_SEARCH | awk '{print $3}'`
ogl_server[count]=`echo $FTP_SEARCH | awk '{print $4}'`
ogl_id[count]=`echo $FTP_SEARCH | awk '{print $5}'`
ogl_type[count]=`echo $FTP_SEARCH | awk -F '[' '{print $1}' | awk '{print $5}'`
ogl_pid[count]=`echo $FTP_SEARCH | awk -F'[' '{print $2}' | awk -F']' '{print $1}'`
ogl_commands[count]=`echo $FTP_SEARCH | awk '{
    for(i = 6; i <= NF; i++) 
        print $i;
    }'`

let "count += 1"

done < /tmp/ftp_search.14-12-02
