Please be patient as it is hard to understand your broken English.
You will have to add those line and increase the values as required.
You have this in the my.ini file and so just add those lines at the end like I have done here and save the file and restart the mysql server.
# The MySQL server
[mysqld]
port= 3306
socket= "C:/xampp3/mysql/mysql.sock"
basedir="C:/xampp3/mysql"
tmpdir="C:/xampp3/tmp"
datadir="C:/xampp3/mysql/data"
skip-locking
key_buffer = 16M
max_allowed_packet = 1M
table_cache = 64
sort_buffer_size = 512K
net_buffer_length = 8K
read_buffer_size = 256K
read_rnd_buffer_size = 512K
myisam_sort_buffer_size = 8M
log_error="mysql_error.log"
max_connections = 200
max_user_connections = 200
table_cache = 1200
The my.ini and the implementation of MySQL is for...
# Example MySQL config file for small systems.
#
# This is for a system with little memory (<= 64M) where MySQL is only used
# from time to time and it's important that the mysqld daemon
# doesn't use much resources.
...if you cared to read the comments in the my.ini file instead of blowing off steam.
