Expected behavior

Regardless of the version of Rocksdb, the overall time required for unit testing should be similar, or is there any configuration that can shorten the time?

Actual behavior

When I was conducting unit testing on Mac OS using different versions of Rocksdb, I found that the overall CI time for version 7.7.3 was much longer than that for version 5.15.10

Steps to reproduce the behavior

@Test
    public void testOpen() throws RocksDBException {
        for (int i = 0; i < 60; i++) {
            long start = System.currentTimeMillis();
             try(RocksDB db = RocksDB.open("test-open-" + i)) {
                 System.out.println("RocksDB.open() cost:" + (System.currentTimeMillis() - start));
             } finally {
                 RocksDB.destroyDB("test-open-" +i, new Options());
             }
        }
    }

My project has many single test cases using Rocksdb, and I hope that upgrading the version can shorten the time. Can you tell me what to do?

Hi @GuipaiQigong111 this looks like you are encountering the same issue as #11035 - unfortunately not an easy fix;
