Yannis,
How is the data structured? Can you give us an example of the queries
that you are trying to run? Do you have indexes in place? A very inefficient
query, or poorly structured database can lead to this type of timeout issue on
the type of low end hardware that you are using.
Thanks,
David

Subject: How do increase memory allocated to MySQL?
Hi everybody,
I have loaded a very big amount of data in my MySQL database (coming from the
YAGO project):
-rw-rw---- 1 yannis admin 65 3 fév 16:07 db.opt
-rw-rw---- 1 yannis admin 6392030392 3 fév 21:35 wasfoundin.MYD
-rw-rw---- 1 yannis admin 11085793280 4 fév 04:54 wasfoundin.MYI
-rw-rw---- 1 yannis admin 8668 3 fév 16:09 wasfoundin.frm
as you can see the MYI file is 11Gb and the MYD file 6.4Gb.
Whenever I try to send a query through phpmyadmin, it crashes and I get
returned to the initial page of phpmyadmin.
When I send an SQL query directly, it works, but it takes many minutes (a
simple SELECT will take about 10 minutes).
I'm using the latest version of MAMP under MacOS X (on a MacBook Pro 2.6 GHz
Intel Core 2 with 4Gb of RAM).
What can I do to make phpmyadmin work? Is it a chance to gain more speed when
interacting through regular SQL queries, or is it hopeless?
Where can I find more information about using MySQL with such big tables?
Thanks in advance
