Subject: IGB slow with large quickloads, even if no annotation is selected

Hi,

I have a strange problem with large quickload servers. I have created a quickload with all results from our group ( > 7000 annotations). As soon as I add it to the data sources, IGB becomes really slow, particularly when searching/zooming. What is strange is that it happens event if I have not loaded any of the annotations of this quickload server. If I remove it it becomes fast again.

Example:

1) Open IGB, select my species

2) Go to advanced search, enter myc, search

3) double click on any of the results -> zoom finish in < 1 second

4) Add my quickload server

5) Go to advanced search, enter myc, search

6) double click on any of the results -> zoom finish in > 4 seconds

7) Remove my quickload server

8) Go to advanced search, enter myc, search

9) double click on any of the results -> zoom finish in < 1 seconds

The same speed difference is observed if I used the method "ServiceManager.getInstance().getService().zoomToCoord()" from my plugins.

Do you know why this happens? Is the quickload server searched even if none of the annotations is selected?

thanks,

Arnaud
