[FONT=Arial]I have a strange problem with both my zencart shops.[/FONT]
[FONT=Arial]http://www.luxim.nl/index.php[/FONT]

[FONT=Arial]That I have both hosted on servage.com
They are installed in separate folders and I have separate databases for each shop.
Many times the pages load within <3 seconds that is sufficient fast for me.
But then at random times the load time dramatically increase.
I see sometime load times of 20 to-30+ seconds and then it is almost always the parse time that is long and the query time rarely goes above 1 sec.
Most times query time is <0.5 sec.

I have beens searching with my hosting provider and they cannot find a thing wrong in the server and now the suspect the script.
I tried new install of the script without customization or addon's I tried installing in a new database ,nothing seems to help

Is there any thing I can do to see where the slow loading is caused?
the version of the Zencart script I use is :
[/FONT]v1.3.7 [2007-04-06 09:07:40]


This problem is driving me a bit crazy:S


Thanks in advance
Is there any suggestion that can help me solve this?
