We routinely put large compressed fastq files into data libraries by that method (linking, no copy) and it is very fast, since the patch that stopped it decompressing the files.
You should probably make sure you specify the file format (fastqsanger) so Galaxy does not attempt to sniff the file to learn its datatype.

Hi Roman,
This is a good question for the development community to provide feedback on, so I'll cross-post your question over to that list.
Best,

Hello,
Today I was routinely adding a 27GB Illumina lane on my galaxy instance running on a cluster node. Just the regular cloned-from-hg type of instance with set_metadata_externally, no more tuning.
It took more than 10 minutes to have the dataset imported into a data library via the filesystem path upload method... not copying it into galaxy, just "linking".

Since I cannot add datasets to libraries in usegalaxy.org and compare, I was wondering if someone can state an approximated average time *for a production* galaxy installation to do that operation.
I would like to have some empirical number to show on how a production deployment[1] could speed things up, as opposed to having individual galaxy instances per user in a cluster (as per IT policies):

Thanks in advance ! Roman
