I'm not sure where my problem lies, but someone here might have a suggestion.
I'm developing a .NET web application, (but I don't really) think that's
relevant.
I'm running MySQL 4.1.7-nt on my laptop, and I'm accessing it through ODBC
(MyODBC-3.51.10-x86-win-32bit).
I already had the application running OK on my desktop, and when I created the
same environment on the laptop, retrieving trivial amounts of data (5 rows) from
a table is taking 6 seconds. Updates the same. IN otherwords any table access
takes 5 or six seconds. (Table only has about twenty rows in it).
I can connect to the database on the laptop from the desktop (i.e - application
runs on desktop, retrieves data from laptop - works fine, not noticeably slower
than local on desktop.
If I connect the other way - application on laptop, database on desktop, it runs
just as slowly as locally.
The effect is the same whether I connect to 127.0.0.1 or via the machine name.
I don't really know where to look. Any suggestions would be gratefully
received...

Jim,
I'm not sure what the exact problem could be, but here are some
ideas to try on your laptop:
- Turn on ODBC Trace.
Go to Start / Programs / Administrative Tools / Data Sources (ODBC).
Click on the Tracing tab.
- I'm sure MySql also has some kind of tracing or logging facility.
You might want to check into that.
- Turn off System Restore.
I encountered a similar problem with Interbase database files that
have a GDB extension. System Restore will backup files with a
certain extension every time they are modified, which can slow
things down a lot if the file is frequently modified.
The file extensions that System Restore backs up are listed in
FileList.xml, located somewhere under c:\windows. Note that this
file cannot be modified. If it is, Windows will simply overwrite
the changes by refreshing it from the system cache.
--
Hope this helps.
Chris.

Hi,
Why use ODBC (the old 3.51) in C#. You can find a free managed
provider (URL http://umn.dl.sourceforge.
net/sourceforge/mysqldrivercs/MySQLDriverCS-n-EasyQueryTools-3.0.16b.
exe) and it's fast.
Best regards

Thanks Chris, I'll give these a go - I think the problem does lie with the OS,
because I changes to a native provider, and the symptoms remain the same.

... though it is discontinued as ByteFX and is now the MySql .NET
provider (downloadable from MySql.org). The problem with the old ByteFX
driver is that it apparently can't connect with the latest mysql 4.1
version (I couldn't get it to work). DId you manage to get it to connect
to a default install of MySql 4.1.1g (the latest I think) with InnoDB?
It kept complaining that my client was out of date, which is an error
which is displayed when you use new password storage settings and an old
client (which I didn't I downloaded the latest stable client/server from
the website)
