Summary
- At this point we can conclude that more-or less safe limit is 8-10 jobs with 1000 orders per organisation
- Most of jobs failed with Connection refused (Connection refused). However it doesn’t looks like it's the matter of FTP server. We did observe same behavior previously with 3-4 parallel job, and it was fixed with increasing of memory parameters on the module side. At same moment we can't see significant resource usage on FTP server side.
