Total Commander

When I switch to thumbnail mode, viewing a list (e.g. 100) of image files (JPG, 1MB+) takes extremely long.

The Windows Explorer is very fast compared to Total Commander and shows the image list very fast.

My suggestions:
- Load the list of visible thumbnails in random order. The Windows Explorer does the same (Windows 7). I can get a better impression of what content the image folder is.
- The Thumbnail viewer should load small images when possible. Many JPG-Loaders offer this low quality mode which is ok for thumbnails. Sometimes there are also tiny thumbnail pictures embedded in JPGs which speeds up loading.

What is your System configuration? What do you use for thumbnails generation? Explorer method only or IrfanView or some plugin?

I have hundreds of 2-10MB JPG files and no "extremely long" situations happen. With thumbnails caching ON, only first folder load takes little longer time but it is still similar to what Explorer does.

I am using Imagine plugin on my AMD 3800+ (2.01GHz) processor with 2GB RAM.

Thumbnails config:

Code: Select all

[Configuration]
PreloadThumbnails=3
ThumbExplTypes=*.* | *.htm *.html *.reg *.mng *.pdf *.ico
ThumbHeightNoCache=128
ThumbIrfXnTypes=*.* | *.reg
ThumbOptions=15
ThumbPlgTypes=*.* | *.psp *.rtf *.reg *.mng *.flv *.icns
ThumbTxtTypes=*.txt *.ini *.csv *.reg *.diz
ThumbWidthNoCache=128
ThumbsCopyDel=1
ThumbsCustomField=[=tc.size.bkMG2]
ThumbsCustomFieldsEnabled=1
ThumbsInDlg=1

I'm using the explorer method only. Not using any plugin for displaying thumbnails.

ok. Now I know why it is sooo slow.

My tcthumbs.idb (thumbnail cache file) is about 500MB big. Seems that thumbnail creation is getting really really slow when the cache becomes too big.

There should be much potential to improve the thumbnail generation speed. Christian could you please look into it?
Was mentioned several times now.

With today's fast computers (dual core or more), you may want to just turn off the cache if you have so many images. I tried with databases, but they really eat a lot of memory.
