Studio links VERY slow - 120 seconds

[tuser13]

So, this is the 3rd time I am trying to set up sugarcrm (Open Source) on a different box, and for some reason, I keep running into this problem.

I am currently running the sugar virtual appliance, and am still seeing this issue:

First, the details:

1)
Apache: 2.0.59
OS: Linux flavor that came with the appliance downloaded from website
PHP: 4.3.11
MySQL: 5.0.24
SugarCRM: Version 4.5.0f (Build 1202)

Also attempted on:
2)
Apache: 2.0.54
OS: Fedora Core 4
PHP: 5.2.1
MySQL: 5.0.37
SugarCRM: 4.5.1b

and
3)
Apache: 2.0.52
OS: Red Hat AS 4
PHP: 5.2.1
MySQL: 5.0.22
SugarCRM: 4.5.1b

Now, for each of these, whenever I would go to Admin -> Studio, click on "Edit Module" -> Leads -> "Edit Custom Fields", the page would take 120 seconds (give or take a few milliseconds) to load. Then I could click "Create Custom Fields", and when I created one and hit "Save", it would take another 120 seconds to return.

On (2), it would not save anything in the database.

There is nothing (no entries) in the mysql slow query log (threshold set to 1 second in my.cnf), httpd error log or access log (no errors, standard access log entries), nothing (no entries) in the php error log (logging ALL), and no spikes in server load for mysql or httpd.

Now, I AM running sugarcrm from behind a firewall at home, and accessing it from outside. So, I am port-forwarding a non-standard port (8080) to port 80.

I have turned off IP address verification in the Admin panel.

Most other queries return in under 0.5 seconds.

I first noticed this problem when I was unable to save custom fields, and then upgraded php, and then finally downloaded the virtual appliance.

Any ideas? This seems like a network issue, but I couldn't say for sure. Turning on stack traces for errors in the admin panel shows a whole bunch of smarty template errors, even on the sugar demo site.

I'm also having a similar problem. It seems to be the result of changing to php 5.0 or greater.

My current setup:

Apache: 2.0.54
OS: Fedora Core 4
PHP: 5.2.6
MySQL: 4.1.2
SugarCRM: 5.0

Did you ever find a solution to this?
