is the objectId is global unique for a storage or it is unique in channel?

Hi @hg-ms @fh-ms
I use microstream as my app storage system, but it become being slow when adding or updating more and more data （ the data size is about 2G( I use one channel)）.

I view the source code and find that when adding a new object or updating the existing one, microstream will consume more time on
one.microstream.persistence.binary.types.BinaryStorer$Default storeItem, specifically on method one.microstream.persistence.types.PersistenceObjectRegistry lookupObjectId

I use 08.01.00-MS-GA. JDK17 and BinaryHandlersJDK8::registerJDK8TypeHandlers.

this.mutex is per StorageManager or per channel? it seems it consumes more time with more and more data in StorageManager

one.microstream.persistence.internal.DefaultObjectRegistry. class
	@Override
	public final long lookupObjectId(final Object object)
	{
		synchronized(this.mutex)
		{
			if(object == null)
			{
				throw new NullPointerException();
			}
			return this.synchLookupObjectId(object);
		}
	}

Do we have some performance guide for large dataset? Thank you!
