When you want to insert larger CSV file in to a mysql database using  PhpMyadmin or any other GUI tools it may take long time or even it  may be stopped. You can easily Import the CSV file in to mysql database using mysql command.  Log on to the server and  open mysql command and log on to the console and do run the following command. I guess the Db name is  testdb

use testdb;
load data local infile ‘CSVFILE.CSV’ into table TABLENAME fields terminated by ‘,’ enclosed by ‘”‘ lines terminated by ‘\n’;

I have seen that when executing a mysql query the cpu usage becomes 100 % and it takes a long time to execute the query.  I have executed the same query thorugh phpmyadmin and that time also it took a long time to execute also mysql consumes 100 % cpu .  I have done some change to my.cnf file and restarted mysql and the problem wentaway.  You can also adjust your my.cnf values as follows.

[mysqld]
max_allowed_packet = 128M
sort_buffer_size = 512M
max_connections=500
query_cache_size = 512M
query_cache_limit = 512M
query-cache-type = 2
table_cache = 80
thread_cache_size=8
key_buffer_size = 512M
read_buffer_size=64M
read_rnd_buffer_size=64M
myisam_sort_buffer_size=64M
innodb_flush_log_at_trx_commit=2
innodb_buffer_pool_size=700M
innodb_additional_mem_pool_size=20M

Once you made the changes in my.cnf do not forget to restart mysql server. Mysql can be restarted in any of the following methods

If you have installed mysql using RPM you can restart mysql using one of the following commands

service mysqld restart  OR /etc/init.d/mysqld restart

If you have installed mysql from source files you  can shutdown mysql and start it as follows

Stop Mysql : mysqladmin -uroot -p shutdown

Start msyql : /usr/local/mysql/bin/mysqld_safe –user=mysql &   (assume mysql is installed at /usr/local/mysql)

Install mysql server on both server and client machine
