Waiting for others upload process to finish

We have several HQ users creating assignments (the goal is to create up to 6.4 million of assignments). The HQ users create the assignments by uploading tab files.

The problem we are experiencing is that apparently SuSo is performing the uploading process sequentially even though we have 10 SuSo servers behind a load balancer. The HQ user has to wait until some other user finishes his/her uploading process. This wait is causing delays in the field work.

The waiting message we are getting is this :

Cola de Uploads

This is by design.

Elsewhere you wrote

Each file contains 2,700 assignments

Consider stacking these files and uploading as 1 single file by 1 HQ user.
