server has become VERY slow, almost unusable

[diegotests]

Hello

Lately the server (s192) has become VERY slow, almost unusable.
Tonight I can't even update a tiny 300 KB file, it takes ages and keeps failing.

My website uses almost no resource though since for now I am the only visitor.
I suspect some other website is abusing and wasting all the server resources.
Please check.

Thanks.

Please run the network test and post here the results.

I must be doing something wrong, it does not find. I opened the firewall though.

My computer generated the report in french with missing characters, sorry for that. Translation : "can't find the server's name", and at the end "timeout".

The network test doesn't show any problem. Which operations are slow exactly? Is the AlterVista control panel slow, or the website (even loading webpages)? Did you try to upload the file through the AlterVista control panel, a PHP script on the website or using FTP?

[diegotests]

Well, I uploaded a html5 project to test how it runs in Android tablets browsers.
It takes more than twenty seconds to load the two tiny ogg files which are just 185 KB and 278 KB.
In the past months I uploaded other games, they were loading very fast. Now they are very slow to load too, like this new one.
I did not make any change to the way I load the ogg files in the game, it is just a usual XMLHttpRequest.
Same website, same tablet, same computer, same game engine, and same 15Mb/s connection, as before.
I suspected maybe Chrome got an update that made it slow to load XMLHttpRequests, but same happens with Firefox.
Here is the link : http://diegotests.altervista.org/htm..._pk_wr__demo1/

Also, for a few days, every time I tried to upload a file, it took ages and keep failing.
I use FileZilla ftp client.
I just uploaded some stuff to try and it seems to work again today.
AlterVista control panel is not slow neither.

But games are still stuck for twenty seconds loading the tiny files.

Let's investigate this: with that webpage I don't experience slow loading and the Ogg resources take less than 100ms to download.
You can get the HAR report here: https://gist.githubusercontent.com/a...2b8f41d8bf/har.
To view it you can use an online tool like http://www.softwareishard.com/har/viewer/.
Please load the webpage with Chrome or Firefox in a private browsing window with the network panel opened, then copy everything as HAR, upload the file somewhere and post here the address.

Here it is : http://diegotests.altervista.org/tem...rvista.org.har

By the way, tonight again uploading files to the server is very slow and had to restart several times. I did run the test again, but all values are still very similar to the one I posted.

[karl94]

Your HAR file shows that you loaded the page in a few seconds. Have you got problems with the loading (dowload) of the page or only the upload?

[diegotests]

Both.
When I recorded the HAR, the files took like 20 seconds to load, mostly the two ogg files. It's strange that the HAR says they were loaded a lot faster. I can't explain what happens.
Then when uploading the HAR file, it was very slow and had to restart twice.

[karl94]

Can you try using a different internet connection?
