[ome-devel] Feedback: write performance

[Rubén Muñoz]

Dear Melissa, Curtis & Josh, 

Following the resolution of the ticket #5965, I have been testing the new 4.3 to convert a medium size dataset (384 planes and 2 timepoints) to a network share.

The command generates multiple OME.TIFs with compression:

bfconvert -compression LZW source/experiment_descriptor.xml target/%n--T%t--Z%z--C%c.ome.tif

The connection to the server is not limiting because copy is faster but previous bioformats versions gave roughly one 1.5MB file (slice) per second converted.

With bioformats 4.3 now 768 images convert in 6 minutes which means more than 2 images per second are read, processed and written.  This depends on conversion used (microscope format) but here the performance increase was 100%. 

The chosen solution was definitively the correct one, the larger buffers seemed to accelerate all the conversion process. 

Once again sincere thanks for your prompt reply and follow up of the incidence. 

Great job!

Rubén
