web site connection slow - apache

I have apache web server and I have a django site on it.
The site use a lot of images (~50) png file.
When I refresh the page it is very slow until it come back again.
I tried to check with google developer tools network view and saw that my site have connection latency when I requesting the images..
I attached the screenshot - it is the top of the list and go on until the end..
Do you have any idea to reduce the delay?

If your images dont change often try using cache control headers so that your browser doesnt get the images from server every time you reload a page

Why does not the page load entirely?

If I load a page on my Drupal 8 site with a reliable internet connection, the site will stop loading after about 20 seconds.
My server is on LAMP. How to get the page to load completely ?
It can be that your theme or some of the user modules is causing the issue.
Check under Reports -> Recent log messages to see if some error is logged.
Also you could try disabling theme or modules (temporary) to see if this will continue.
Then, under Configuration -> Development -> Performance see if the caching is turned on. It should be on for production environment.
In your browser go inspecting, go to "Network" tab and reload the page. See if there are some request that take unusually long time.
Ask some of your friends to test the site.
At end, host server may be really slow or miss configured... Check for logged errors on server (PHP errors, Apache errors).

web pages stuck on "waiting for...", but then load fast

My website has a huge data base. Even this the frontpage with all content is 1.2MB. Small. I changed server because I wanted to load faster. In the old server when I clicked the url the site started to load serially, from the top to bottom. But in the new server I get the message "waiting for www..." in my browser down left for 4-5 sec and then my website displayed very quickly. When I remove one big mysql query, it is OK.
I downloaded the htaccess of boileplate, I put in Plesk hosting settings FastCGI application, but nothing.
Any idea?
If you are getting this issues due to mysql query then I will suggest you optimize your mysql services with MySQLTuner scripts. We have used that on for our some clients and it's working good. But make sure your mysql service up-time is more than 24 hours, so that you will get accurate suggestions in the script output.

Dev tools not showing insecure content loaded in via javascript

I work with a lot of SSL/https pages that must be 100% secure so the lock is green and not yellow.
It's easy to pinpoint any 'dom level' scripts or images, because console puts out the error 'this page is loading insecure content from __'
The problem is when a secure https script loads NON-https image/script... it doesnt seem to be logged in chrome dev tools console as an error for loading insecure content. The only way to see it is if i manually move the mouse over like 80 different asset links, tracking pixels, etc and making sure it starts with https
Does anyone know a better way of handling this? Thanks!
In Firebug you can enable the display of a Protocol column. To do so you have to right-click onto the column headers inside the Net panel and click on Protocol. Then you can sort by that column by clicking on it's column header.
Doing so it should be pretty easy to spot the insecure request.

Apache error log showing very strange problems

I was wondering if anyone could point out what is causing the problem in the screenshot attached. It has happened a couple of times with different images. I can't see what is causing it.
The machine is my development machine.
I was hoping to post this on serverfault but I can't add the image I need.
Not enough info yet, so just some debugging steps.
Try uploading it to a different machine and see if you get these same messages.
Check you don't have any Javascript doing anything with image urls - to me it looks like some loop somewhere might be going 'wacko', but could be client or server side.
Use tail -F on it in the terminal and refresh the page to see if the appearance of those entries coincides with the loading of the page.
Edit: maybe also have Firebug/etc open when you refresh the page with their Network panels open to see if you really are sending those requests. Really just want to find if it's a client or server issue to begin with.

My server intermittently won't serve pages to Safari 4... Need help!

I just upgraded my browser to Safari 4 and find that our website is having some major issues specific to that browser version. As I click through pages on our site it takes one or two clicks before the browser window simply goes blank. When the window goes blank, there is no source to view and no matter how many times I try to reload or if I try to load other pages of the site, I still get the blank window. It's as if the server takes the request and simply returns a blank page.
If I wait over 15 seconds and then hit refresh again, the page loads fine. Not sure why it starts working again... Maybe a cache issue???
It's a PHP site and I've tried turning on error_reporting(E_ALL);, but that doesn't give any information. I also tried putting an echo statement at the very beginning of the index.php file and verified that the page still goes blank without echoing that statement, so I'm thinking the problem is not php code specific. The Apache error log does not show any issues. I have the same site on my local development server and it doesn't have the problem.
Safari 4 is the only browser that shows this problem. Does anyone have any ideas how to debug/fix this?
My webserver is ubuntu Hardy running Apache 2 an Mysql 5.
We have an nginx load balancer in front of the apache server and I just figured out that Safari 4 requires the nginx keepalive_timeout setting to be 0. Took all day to figure that one out...
I've been having the same issue with Safari 4 on my site but found that when reloading pages that return blanks, the request never even makes it to the server. No entry shows up in Apache's logs.
The keepalive setting for your LB sounds like a direction I could sniff in. Not sure what leeway I will have though, being on shared hosting.

This looks to be a safari bug. We experience it too, and I have read other reports.
