dcmsnd -fileref speed

[Bartosz Wiklak]

Hi,

I'm testing migration from old pacs to dcm4chee. I have created new file system with a directory pointing to where the old images are and send them using "dcmsnd -fileref" command.

My timing results are:

Scanned 1734 files in 7.399s (=4ms/file)

Connected to ARCHIMEDIC@localhost:11112 in 0.133s

Sent 1734 objects (=869.2189MB) in 83.599s (=10.397479MB/s)

Is there a way to fasten migration speed? I tried to increase log levels but it did not help.

[Alvaro G. [Andor]]

Run multiple sending proccesses at the same time. DICOM protocol isn't very efficient sending images, specially if they are small files (see MRI or CT instead of Chest CRs or mammo). Divide the data in several folders and run a dcmsnd process for each folder.

Thanks!
