Summary

Differences in times of execution between stand alone job and multitenant 4-5 times (1 min 14 s for 5 k and 5 min 30 s for 5k in multitenant, 2 minutes to 7 minutes in 10k )
It’s not so stable when it comes to big files we saw a lot of DB timeouts (so maybe it will be a good idea to extend timeouts or investigate them deeper)
We can see memory usage growing from test to test it might be a sign of memory leak.

Multitenant Marc authority imports 2 tenants

Test	Tenant 1	Tenant 2	1 tenant (Controlled)
Test	Durations
5 K	2 min 50s	2 mn 51 s	1 min 14 s
10 K	5 min 23 s	5 min 14 s	2 min 32 s
25 K	14 min 03 s	12 min 53 s	6 min
50 K	24 min 40 s	24 min 37 s	12 min

To test this we've used three tenants with shared resources.

Test	Tenant 1	Tenant 2	Tenant 3	1 tenant (Controlled)
