Thanks Greg, there would be about 100 datasets in the library.

Can you tell me how I would pull a single changeset, I have only done batch updates using the distribution depository before.

I'm just wondering why it has become so much slower since the latest update (I previously updated last December). Also wondering why the Galaxy process is now taking up 25% of the memory on a 64GB machine.

Thanks
Shaun

Hi Shaun,

Security checks are performed on every active ( undeleted ) dataset within a data library as it's contents are rendered upon opening. For the current user, every dataset is checked to determine if the user can access it, and if so, then checks are made to see if the user has permission to perform operations on the dataset that fall into the add / modify / manage permissions areas. These checks incur db hits for each dataset, so if your data library include many datasets ( several hundred or more ), then it will take a bit of time to render it upon opening. The size of the dataset files is not an issue here, but the number of datasets within the data library.

A solution to this is to split up the data library. Change set 5200:ed7b6180b925 added the ability to move data library items within a library or between libraries, providing a way to split up a large library. This change set should make it to the distribution within the next few weeks, or you can pull it from our development repo.

Thanks Shaun,

Greg Von Kuster

Further to my email below.

I have a data library that contains many ~117Gb of NGS data, uploaded via file system path. This library was always slow to open (about 10s) but now takes several minutes or not at all.

Thanks for any help on this. I am still experiencing a memory leak that I can't pinpoint and it is only dissipated by restarting the server. At the moment my debugging level is set to INFO. Is there anything I can change in the universe file to try to trace this.

Thanks!
Shaun
