I have having issues with mysql db - I am doing a "select count(*) from
table" -- and it take 3 to 4 min.
My table has about 9,000,000 records in it.
I have noticed issues on my web pages so that is why i did this test.
I have about 4 gig of memory on the server.
Is there anything I can do to fix the issue ????
My my.cnf looks like this :
# * Fine Tuning
#
key_buffer = 256M
max_allowed_packet = 16M
thread_stack = 192K
thread_cache_size = 32
# This replaces the startup script and checks MyISAM tables if needed
# the first time they are touched
myisam-recover = BACKUP
max_connections = 100
table_cache = 1024
thread_concurrency = 20
#
# * Query Cache Configuration
#
query_cache_limit = 1M
query_cache_size = 512M
#
# * Logging and Replication
#
# Both location gets rotated by the cronjob.
# Be aware that this log type is a performance killer.
# As of 5.1 you can enable the log at runtime!
general_log_file = /var/log/mysql/mysql.log
general_log = 1
#
# Error logging goes to syslog due to
/etc/mysql/conf.d/mysqld_safe_syslog.cnf.
#
# Here you can see queries with especially long duration
#log_slow_queries = /var/log/mysql/mysql-slow.log
#long_query_time = 2
#log-queries-not-using-indexes
#
# The following can be used as easy to replay backup logs or for
replication.
# note: if you are setting up a replication slave, see README.Debian about
# other settings you may need to change.
#server-id = 1
#log_bin = /var/log/mysql/mysql-bin.log
expire_logs_days = 10
max_binlog_size = 100M
#binlog_do_db = include_database_name
#binlog_ignore_db = include_database_name
#
# * InnoDB
#
# InnoDB is enabled by default with a 10MB datafile in /var/lib/mysql/.
# Read the manual for more InnoDB related options. There are many!
#
# * Security Features
#
# Read the manual, too, if you want chroot!
# chroot = /var/lib/mysql/
#
# For generating SSL certificates I recommend the OpenSSL GUI "tinyca".
#
# ssl-ca=/etc/mysql/cacert.pem
# ssl-cert=/etc/mysql/server-cert.pem
# ssl-key=/etc/mysql/server-key.pem
