Insert image performance extremely slow

Reply Quote

I'm running cuteeditor 6.6 within yetanotherforum 1.9.4 using: http://cutesoft.net/forums/thread/49876.aspx . Hosted on GoDaddy running IIS 7, .net 3.5

THe editor box usually loads within 2 or 3 seconds, but when invoking the 'insert image' icon on the toolbar, the dialog takes 10-20 seconds to render, and images are extremely slow to upload.

Running 'view source' on the insert image dialog yields:

which seems fast, but the dialog box itself is still taking 10-20 seconds to display fully.

any ideas why?

RichP714,

Do you have the same problems with the following example?

http://cutesoft.net/example/general.aspx

How many images in the image gallery folder?

Can you upload a simple example page to your server and try again?

<%@ Register TagPrefix="CE" Namespace="CuteEditor" Assembly="CuteEditor" %>
<%@ Page language="c#"%>
<html>
<head>
</head>
<body>
  <form id="Form1" method="post" runat="server">
   <CE:EDITOR id="Editor1" Autoconfigure="Simple" runat="server"></CE:EDITOR>
  </form>
</body>
</html>

Your demo page works fine:

3032 files in upload folder (it's the editor for our forum software so lots of pics)

the sample page performs sluggish on my site as well.

Too many pics in the upload folder?

I changed the upload directory to a new (empty_ folder and response is snappy again. since the dialog was loading in about 60milliseconds, I'm assuming the lag was due to listing the 3000+ images in the file list.

Is there any way to 'disable' the left half of the 'insert image' screen so it doesn't have to pull the folder contents?

This 'problem' is back ,and the only solution seems to be to create another upload folder once the number of images reaches a certain threshold.

I don't want to end up with /uploadimg, /uploadimg2, /uploadimg3, etc folders.

My original 'style="display:none' on the insertimage.aspx file to hide the folder list doesn't seem to have fixed this issue (after the folder has a few thousand images, load performance of the insert image pop up is sluggish)

Is there another way to relieve CE of having to deal with large folders OTHER than display:none?

Can I prevent insert image dialog from doing the work of sorting and displaying the filesandfolders list using Dialog_InsertImage.js? If so, does anyone know how?

Has this issue ever been satisfactorily resolved? I too have this issue with cute empbedded in a ASP.NET. There appears to be a threshhold for nomber of images for us as well, and creating new folders is not an acceptable solution. All image gallery dialogs would probably perform better is views were paginated with sortable columns (that default to most recently uploaded/changed), alphabetic filtering, and a search box.

Has cute tested this with a scale of thousands of images?

What specific changes in the latest version address this issue? Upgrading embedded software is an expensive undertaking and I'd rather not do it unless I am sure the image gallery performance problem is solved.

bpeery,

In this major version release, we totally rewrote the whole application.Actually it's not a simple upgrade. It's a new software installation. You have to remove the old product first and install this RTE 8.0.

Did you redesign the image gallery UI? Because without a redesign of the UI, performance is still likely to decline when the number of images in a specific directory reaches a critical threshld.

bpeery,

Yes, the image gallery UI is redesigned. We also do a full test by putting many images into the same folder.

Is the screenshot below of the updated image gallery?

If it is, I see no reason to believe it will be any more performant because it lacks all of the UI elements I described previously that would allow the UI to scale.

bpeery,

Yes. It is the new version.

This new image gallery uses an endless pagination approach like google images.

Please download the product and test the performance on your local server and you should find the big difference.

Then perhaps it might work. Did I understand you correctly, that you plan to add a very large number of images to the gallery demo to see how it performs?

bpeery,

I copied 4096 images (245MB) to the uploads folder , and try to load it .

It spend 86 seconds to initialize the thumbnails.

(which means about 20ms per photo with 60K size)

And it take only 2 seconds each time I reload it .

(include 1.57M text data)

So now we add gzip feature for the ajax data, and reduce the 1.57M to 21K.

(We will provide this feature in 24 hours)

Regards,

Terry.

bpeery,

We have released a new minor version.

The new version have much better performance.

The ajax response now is compressed, and the server thumbnail performance is increased about 75%
