Hello @Bernhard_Suttner ,
I just applied this patch and it’s like night and day, thank you for that 
Before:
[PRD root@updates ~ - 09:47:55][0][0]# time hammer --no-headers content-view list --organization-label <my org> --fields "Content View ID" --noncomposite 1
Error: Timed out reading data from server
real 4m8.128s
user 0m1.546s
sys 0m0.265s
After:
[PRD root@updates ~ - 10:15:36][3][0]# time hammer --no-headers content-view list --organization-label <mt org> --fields "Content View ID" --noncomposite 1
(list of ids)
real 0m11.750s
user 0m1.585s
sys 0m0.208s
The web interface is also very fast.
The only downside I see is that on the web interface for the non composite CV the column Latest version has the message Not yet published
But hammer shows that info.
[PRD root@updates ~ - 10:28:01][3][0]# time hammer --no-headers content-view list --organization-label <my org> --fields "Content View ID,Last published" --noncomposite 1
