Delete is very slow
Hi
I have mySQL 4.1.7 installed in W2k SP4, etc, 512 M of RAM and Pentium IV HT 3.2 MB (equiv to 2 CPU). I'm also a new user. I'm testing a 4 M register table with InnoDB and MyISAM. I find mySQL extremely slow. The table has 20 fields and 14 indexes, all RTREE. The DELETE operations are very very very slow. To DROP this table (InnoDB) has taken 10 hours.
This is an abstract of my.ini
[mysqld]
basedir=c:/mysql
datadir=f:/mydata/data
memlock
skip-locking
key_buffer = 128M
max_allowed_packet = 1M
table_cache = 256
sort_buffer_size = 1M
read_buffer_size = 1M
read_rnd_buffer_size = 4M
myisam_sort_buffer_size = 64M
thread_cache = 8
query_cache_size= 16M
thread_concurrency = 8
log-bin
server-id = 1
innodb_additional_mem_pool_size = 16M
innodb_buffer_pool_size = 128M
innodb_data_file_path = ibdata1:10M:autoextend
innodb_file_io_threads = 4
innodb_thread_concurrency = 16
innodb_flush_log_at_trx_commit = 1
innodb_log_buffer_size = 8M
innodb_max_dirty_pages_pct = 90
innodb_lock_wait_timeout = 120
[mysqldump]
quick
max_allowed_packet = 16M
[mysql]
no-auto-rehash
[isamchk]
key_buffer = 128M
sort_buffer_size = 128M
read_buffer = 2M
write_buffer = 2M
[myisamchk]
key_buffer = 128M
sort_buffer_size = 128M
read_buffer = 2M
write_buffer = 2M
[mysqlhotcopy]
interactive-timeout
Thanks you
