Each image loads sequentially. Can it load images simultaneously? about cornerstonedemo

I believe those are prefetch requests which are in fact sequential to avoid flooding the network. The thumbnails should load in parallel and multiple viewports should too

Looking at the network graph on the developer tools, I see that images are being loaded sequentially:

Can they be loaded simultaneously? Would this increase performance?

From my own experience, you will get a huge bennefit from issuing multiple concurrent prefetch requests. Just pull them and cache them immediately on disk, if you can. On a 100 MBPS network,
you can easily make 5 concurrent CT slice requests and not max out the bandwidth. And 1 GIG is pretty common these days. You probably don't want 5 concurrent MG requests, so the prefetch needs to be smart enough to throttle by modality.
