I belong to the biomedical reserch group at CRS4, a research centre in
Italy; we are currently using omero in several projects and we are
running some performance tests during these days.<br>We noticed that the
server has low performances when loading a large amount of data (I
tried to load the meta-informations for 50.000 4-channel images).<br>
I did a smaller test loading 1000 images using a python script and it
took 1 minute and 42 seconds to load the data (as said before, I only
wrote the meta-data of the images into the database, the real pixels
are stored into a HDFS file system). I used the compiled version of
Omero downloaded from the website and with default configuration. Omero
runs on a Linux server (Fedora core 11) with a dual opteron processor
(248 model) and 4GB of RAM.<br>
I'm wondering what is the problem and if there are some hints to
improve the performances on the server. Any help is appreciated.<br><br>Please see the script I'm using, as per attachment (maybe is the script itself my problem).<br>
<br>Thanks for you attention<br><font color="#888888"><br>Luca
