I had actually thought that the new setup against a KVM server from my hoster but with HDD RAID10 instead shoulb be habe similar performance. As I know only B2C SSD were installed therefore the performance should be similar, or not?
On the new sevrer WD hard disks is installed in the server.

General recommendations:
Control warning line(s) into /var/log/mariadb/mariadb.log file
Control error line(s) into /var/log/mariadb/mariadb.log file
Set up a Password for user with the following SQL statement ( SET PASSWORD FOR 'user'@'xxxxxxxxxx' = PASSWORD('secure_password'); )
Restrict Host for user@% to user@xxxxxxxx
MySQL started within last 24 hours - recommendations may be inaccurate
Enable the slow query log to troubleshoot bad queries
Reduce or eliminate unclosed connections and network issues
Configure your accounts with ip or subnets only, then update your configuration with skip-name-resolve=1
Adjust your join queries to always utilize indexes
When making adjustments, make tmp_table_size/max_heap_table_size equal
Reduce your SELECT DISTINCT queries which have no LIMIT clause
Performance shouldn't be activated for MySQL and MariaDB 5.5 and lower version
Consider installing Sys schema from https://github.com/mysql/mysql-sys
Variables to adjust:
query_cache_type (=0)
query_cache_limit (> 512M, or use smaller result sets)
join_buffer_size (> 1.0M, or always use indexes with joins)
tmp_table_size (> 64M)
max_heap_table_size (> 64M)
performance_schema = OFF disable PFS
innodb_buffer_pool_size (>= 1G) if possible.
innodb_log_file_size * innodb_log_files_in_group should be equals to 1/4 of buffer pool size (=128M) if
