Importing large amount of data to database

Hi, I have 2 server (Hyper-v VM with 16 vcore and 16 Gb Ram) with MariaDB 10.6.11 but both have a bad value on “Importing large amount of data to database”,
This is my configuration:

[client]
port=3306
socket=/run/mysqld/mysqld.sock

[mysqld_safe]
socket=/run/mysqld/mysqld.sock

[mysqld]
user=mysql

socket=/run/mysqld/mysqld.sock
port=3306
basedir=/usr
datadir=/var/lib/mysql
tmpdir=/tmp
lc-messages-dir=/usr/share/mysql
log_error=/var/log/mysql/error.log

symbolic-links=0
local-infile=0

innodb_flush_log_at_trx_commit=0

sql-mode="NO_ENGINE_SUBSTITUTION"

innodb_log_buffer_size=512M
disable_log_bin

innodb_io_capacity = 2000
innodb_io_capacity_max = 5000
innodb_checksum_algorithm = crc32
innodb_log_compressed_pages=OFF
innodb_change_buffering=all


!includedir /etc/mysql/conf.d/
!includedir /etc/mysql/mariadb.conf.d/

Do you have any advice?

Thank you a lot!
