Each release of Exchange will include content enhancements around some core content.

In the latest Exchange Server 2019, Microsoft's vision is from the following aspects:

So today let's talk about performance enhancements. The official document of Exchange Server 2019 reads as follows.

What are the new features when upgrading from Exchange 2016 to Exchange 2019?

Performance

Improved search infrastructure: the fully rebuilt cloud size and reliability search infrastructure in Exchange Online now applies to Exchange 2019. With this new search infrastructure, you can index larger files, simplify management, and improve search performance.

Faster and more reliable failover: significantly faster and more reliable failover between servers can be achieved with changes to the search architecture.

Metacache database: improvements to the core of the Exchange database engine improve overall performance and leverage the latest storage hardware, including larger disks and SSD.

New hardware support: Exchange now supports up to 256 GB of memory and 48 CPU cores.

Dynamic database caching: the information stored procedure uses dynamic memory cache allocation to optimize memory usage to activate database usage.

As you can see from above, there have been great changes in hardware support. Exchange Server 2019 now supports 256 GB of memory and 48 CPU cores. I still remember an article I wrote earlier about the changes in Microsoft's 20-year architecture, in which when I wrote Exchange Server 2013, I told you that Microsoft began to enter the stage from division to integration, dividing the CAS,MBX,UM,HUB integration in Exchange 2010 into CAS and MBX, further integrating to Exchange Server 2016, and further merging CAS and MBX, leaving only one MBX. Why would you do that? Due to the development of today's hardware, high-performance servers have been able to meet our needs, so we must support high-performance server configuration, so Exchange Server 2019 hardware support has been upgraded again.

Hardware support is not only experienced in CPU and memory, but also reflected in disk. With the increasing popularity of SSD, we can make full use of the advantages of SSD in Exchange Server 2019, such as putting key search and index into SSD to make login and retrieval faster. Of course, we can still use cheap storage to save mailbox databases.

In addition, with the development of information technology, users' mailboxes are getting larger and larger, that is to say, more and more data are stored in mailboxes. How to improve search performance in a large mailbox environment is also where every version of Exchange Server has been focused on optimization. So when the Exchange Server version is released these years, search will be mentioned, and Exchange Server 2019 is no exception. The biggest change is that search has borrowed Bing search technology, Microsoft said. Will make the search faster and more accurate. Moreover, the index used for search will exist directly in the database itself, without a separate index file, which can speed up the efficiency of database failover and simplify management.

Finally, let's take a look at the scale of Exchange Online.
