Hi Rolando,
Thank you for your help.
I am on MySQL 5, and I have tried to do the conversion using ALTER TABLE
command. With the same very slow result.
Do you by any chance have specific suggestions how to tweak varia

You may also want to tweek the innodb
system variables (show variables like 'innodb%)
for better InnoDB performance prior to trying this.

Well the applications with persistant connections is a touchy subject.
Our apps send and rec data over satelite links which are very expensive.
The shorter the duration of the link the less it costs us. So the
pervailing theory is that with persistant connections the apps will

So without going into specifics here... your sort_buffer and
read_buffer become pretty much unimportant if you move everything to
InnoDB... keeping in mind the earlier advice to leave the mysql

Also a show status gave me a max_used_connections of 236.

The system is only used as a database server, it's a dual processor
system with 2gig of ram.
As you can see, Table1's MyISAM data file is quite large at 2.1 gig.
Taking this into account what size InnoDB data files should I configure

Ok so I'm about to convert two tables in my database from MyISAM to
InnoDB. They are currently:
14K Sep 15 13:15 Table1.frm
2.1G Sep 28 14:15 Table1.MYD
198M Sep 28 14:15 Table1.MYI
11K Sep 20 08:45 Table2.frm
424K Sep 28 14:15 Table2.MYD
110K Sep
I see that the thread is getting too long, so I'm cutting out parts that
I'm not responding to. Hope no one minds.
As far as
I'm concerned, simplicity and ease would be to leave it as is but
we're looking to eek out as much speed in our transactions

You will need to make sure you have innodb configured in the my.cnf
file and you have enough space built for it in the shared table
space. InnoDB also needs it's own memory pool, so make sure you give
it enough memory. For day to day issues there is no problem doing

If you want to use InnoDB, you should install MySQL-Max binary:
