MySQL is eating up nearly all the CPU all the time. How does one go about diagnosing this issue? Here are the vital statistics:
Our machine:
Windows Server 2008 R2 Enterprise
Intel G6950 2.80GHz
4GB RAM
64-bit
MySQL Server 5.5
ASP.NET v2.0
From my.ini:
character-set-server=latin1
default-storage-engine=INNODB
sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"
max_connections=500
query_cache_size=256M
table_cache=320
tmp_table_size=195M
thread_cache_size=8
myisam_max_sort_file_size=100G
myisam_sort_buffer_size=256M
key_buffer_size=1024M
read_buffer_size=64K
read_rnd_buffer_size=256K
sort_buffer_size=256k
innodb_additional_mem_pool_size=12M
innodb_flush_log_at_trx_commit=1
innodb_log_buffer_size=7M
innodb_buffer_pool_size=1024M
innodb_log_file_size=117M
innodb_thread_concurrency=8
external-locking
The table that is accessed most often and seems to be slowing down the works is asset_search_asr
