Runner, Time of deploy

Last month I have problem with time of runner (CD, deploy).

1 month ago was time of deploy ( - lftp -c “set ftp:ssl-allow no; open -u $ftp_user,$ftp_password $ftp_host; mirror -Rev public/ ./www --ignore-time --parallel=10 --exclude-glob .git* --exclude .git/ --exclude subdom/ --exclude .htaccess”)
max. 5 minuts, now is time cca 3 hours.

Process of removing and transferring files has longer time than 1 month ago.

Runner now is for example: Runner: #12270840 (-AzERasQr)

1 Month ago was runner for example Runner: #12270852 (Jhc_Jxvh8)
