             Summary: performance drop on PME time during 1 server node left

                 URL: https://issues.apache.org/jira/browse/IGNITE-10284

7 server nodes (1 node per host), 120 caches, G1GC, 32768 partitions 1 client tx loading

1. start cluster, fix baseline, preload data
2. start tx transfer task
3. kill 1 server node
4. wait for topology snapshot change, measure PME time
5. restart killed node
6. wait for topology snapshot change, measure PME time

for 1 server LEAVE, we see 7%-10% degradation, BUG

for 1 server JOIN, we see performance degradation on first exchange (evt=NODE_LEFT) and performance increase on second exchange (evt=CacheAffinityChange), overall 40-60% increase.
