Description

I experience that my site's file galleries get slower and slower. Currently, there are just about 200 Mbyte of mostly images in there, in just about two dozen folders. Although my rented web space will of course not boast performance wonders, but it should't be THAT slow. When I clear caches, just calling file galleries takes up to three minutes. If cache has not been cleared, galleries come up instantly.

I have stopped using tiki-check.php even before that, because it regularly breaks my ISPs five minute quota...

I store the images in the DB, but I don't think this really makes the issue. The DB still has almost a terabyte of available storage. And a DB's speed shouldn't depend on amount of storage taken, but on complexity of SQL requests.

I believe that most of the current slowness came when I uploaded some graphics for my co-admins that are not large in size, but large in dimensions (300 kbyte, but 14,000 x 10,000 pixels) (logo master file in PNG). For them, thumbnail creation fails. Could it be that Tiki tries to generate those thumbnails all the time, and fails?

Thanks

Demonstrate Bug (Tiki 19+)
This bug has been demonstrated on show2.tiki.org
 Accessing the Tiki instance that demonstrates this bug

The URL for the show2.tiki.org instance that demonstrates this bug is at: http://hman-11504-7710.show2.tiki.org. Note that if you get a popup asking for a username/password, please just enter "show" and "show". This is different from the initial login and password for a new Tiki which is "admin" and "admin".

For the install log, see http://hman-11504-7710.show2.tiki.org/info.txt

Note that if you see PHP errors or a Tiki claiming to be missing third party software, the instance creation is probably not finished. Please wait a couple minutes and reload.

 Snapshots

Snapshots are database dumps of the configuration that developers can download for debugging. Once you have reproduced your bug on the show2.tiki.org instance, create a snapshot that can then be downloaded by developers for further investigation.

Snapshots can be accessed at: http://hman-11504-7710.show2.tiki.org/snapshots/. Note that if you get a popup asking for a username/password, please just enter "show" and "show".
