Yes, other tests ran 60 seconds too.

I am attaching results of tests for 32 and 128 clients that were running for 10 minutes, and TPS remains 305 and 115
ktpsrespectively.
Tests was executed with configuration set for YCSB. And there is very aggressively autovacuum, this can be reason why
thereis no decline appears with increasing working time.
Autovacuum config:
autovacuum_max_workers = 8
autovacuum_naptime = 10s
autovacuum_vacuum_scale_factor = 0.1
autovacuum_vacuum_cost_delay = 0ms
autovacuum_vacuum_cost_limit = 10000
