Well, connecting to a ODBC source my hd start to swap too much
and I load pages (on the local machine) at 1.5 kb/s.
PHP run on a NT box with Apache 1.3b6

This script reproduce my problem:

<? 

	$dbh = odbc_connect($dsn,$usr,$pwd);
	$result = odbc_exec($dbh,$query);
	odbc_fetch_row($result);
	echo ">>";
	echo odbc_result($result,0);
?>

Configuration:

PC Pentium 133MhZ 32Mb Ram
Windows NT 4.0 sp 3
PHP 3.0RC4
Apache 1.3b6
The odbc driver is MyODBC 2.50.15 for NT

The binary and the php.ini file are unmodified from the
distribution file.

P.S.: Connecting directly to the MySQL server with the mysql
functions this problem doesn't appear.

Best Regards
Andrea Bettarini

Closing due to lack of useful information.  For all we know, you could be selecting 10Gig of data on a machine with 32 mb ram.

Here are some things to try:
use an access or dbase odbc connection with the same data and query and see if it has the same results.  If not, MyODBC is the culprit, if so, you'll have to give some idea as to the size of the data being selected, number of rows, what the sql statement is.  The sample script provided does not work 'as-is'.
