Backlight slow down after adding a lot's of album sets & albums

Hi!

I have create now me new website and after some trouble wie die response time of the home page I set up a new version with a clean Backlight Installation and create only the needed templates.

The empty testside is avalibel here: http://gosslar.homedns.org:8888/

Then I make a copy of all and start to put the full content in the side. Currently I have

normal side:
Album sets: 230
Albums: 438

The testside has:
Album sets: 19
Albums: 37

And I see, that the homepage needs more time to answer. I measure with firebug the following times for the answer of the first get for the homepage

http://gosslar.homedns.org/ 4357ms
http://gosslar.homedns.org:8888/ 368ms

The effect is only seen on the homepage, all other requests on some galleries have the same speed

Both sides are running on the same server, I measure the sames behaviour every time, check it also from different network provider. All times I see the same result. The side with a lot of albums is slow and I think if I add more pictures/albums the spped goes down again.

So my question is, how can I fix it? Or is a workaround avalible (without removing the albums). Is there a logfile, where I can check what is need more time? I found only the logfiles for the publisher and the designer, but not for the running system.

Bay the way. In the apache log files I see, that these file is missing (on both server)

backlight/publisher/vegas.min.js.map

I found only a vegas.min.js file. Have a make something wrong? But I think, this is not the reason for theslow down of the speed, because the file is missing on both server.

Thanks for the help!

Visiting your site, I'm finding nothing out of the ordinary. Your home page and galleries are loading as I would expect.

Lovely landscapes, by the way.

Lovely photos! I've run a test on your site to check for database performance, and it seems to be running well, so that is not an issue.
FYI, the link to check that is http://gosslar.homedns.org:8888/?performance&skipCache. The result that indicates the speed is the line "http://gosslar.homedns.org:8888/?performance&skipCache". I'm seeing 60 milliseconds, which is fast.

Hm, maybe I describe it wrong

Ah, great check and I see, what I describe wrong. Both side have the same layout, side on port 8888 is fast and the normal webpage slow. Only the number of include pictures, albums and album sets are different. With the commandline I check it and see these:

Testside, same layout, less albums I measure this:

Normal side, a lot of album sets and albums

time taken to query Publisher1: 64.126968383789 milliseconds <<< testside, some albums
time taken to query Publisher1: 1776.4070034027 milliseconds <<< normal side, a lot of albums

The same time difference I see more the one time in the log. These matchs also with the timing from firebug:

timing for load the testside, the browser wait 0,3 sec for the answer (german "warten")

timing for load the normal side, the browser wait 5,5 sec for the answer (german "warten")

And 5 sec. before the first picture is seen is too long I think, especially when the connection is fast, the server also.

Christian
