OK, so this isn't really a PHP question, but since a large number of you are running the same configuration that I am, I figure this is the best place to ask.
I have two servers that know nothing about each other at all. In fact, they are in two physical locations and never connect to one another.
The first is a P3-733 MHz with 128mb of RAM. It runs Red Hat Linux 7.3, and the latest versions of Apache, MySQL, and PHP. Other than PHP v4.2 being picky about global variables, etc. I have no problems with this machine and this configuration.
The second is a P2-233 MHz with 64mb of RAM. It runs Red Hat Linux v7.2 and the latest version of Apache, MySQL (from about 9 months ago), and PHP v4.1.x (don't know offhand, but it doesn't have the same quirks about global variables as 4.2.x does).
On the second box (listed above) I can have Apache serve both HTML and PHP documents without a significant delay. However, if inside a PHP document a call is made to the MySQL server for information (such as a login screen or a query to a table for results) I get a SIGNIFICANT delay, like 60-90 seconds per query. Any idea why this would only happen on my SQL queries?
