[ome-users] Can somebody explain the pyramid building concept to me?

[Jake Carroll]

Hi all.

I'm currently trying to understand some of the time-frames it takes to ingest big images into Omero. We're putting a 9.8GB image in currently, and it looks like it'll take a very very long time. We've thrown 16GB of RAM at it, 4 * vCPU's and copious amounts of high speed hardware.

drwxrwsr-x 2 linuxadmin staff  4.0K Aug 28 14:45 .
-rw-rw-r-- 1 linuxadmin staff     0 Aug 28 14:45 .201_pyramid.pyr_lock
-rw-rw-r-- 1 linuxadmin staff   80M Aug 28  2012 .201_pyramid4066596291236323213.tmp

Found that in the "Pixels" directory.

It generates ever so slowly.

So I have a better handle on it all, can somebody explain why it's such a slow procedure? It's barely using any CPU time or RAM currently. Perhaps it's my lack of understanding as to how the rendering/generation works that makes me perceive it as "slow".

Thanks!
