I've installed Xampp for Windows version 1.7.2 and located the settings file at C:\xampp\mysql\bin\my.ini
I've got a large database (20 million records) and am running PHP scripts (I've adjusted php.ini) that are quite demanding - e.g. updaing or looping through all records.
I'd really appreciate any advice people could give as to changing the settings of my.ini to speed things up as much as possible - unfortunately I don't really know much about memory sizes.
The values that I (think) I might need to change are:
- Code: Select all
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
[mysqldump]
quick
max_allowed_packet = 16M
[mysql]
no-auto-rehash
# Remove the next comment character if you are not familiar with SQL
#safe-updates
[isamchk]
key_buffer = 20M
sort_buffer_size = 20M
read_buffer = 2M
write_buffer = 2M
[myisamchk]
key_buffer = 20M
sort_buffer_size = 20M
read_buffer = 2M
write_buffer = 2M
[mysqlhotcopy]
interactive-timeout
(In case it helps, I have a Windows Vista 32bit, Dual Core Processor with 3.5GB RAM). Could anyone recommend what settings I should change and the possible values that they can go up to? Thanks
