-#### Parallel compression of memory dumps
-
-To generate dumps faster and make them smaller in size, a compressed memory dump feature was introduced in SQL Server 2022 CU8 and SQL 2019 CU23. When activated, Sqldumper.exe creates multiple threads to read a process's memory simultaneously, compresses it, and then saves it to the dump file. This multi-thread, parallel compression reduces file size and speeds up the dumping process when used with full and filtered dumps.

-You can turn on trace flag 2610 to enable compressed memory dump:
-
-```sql
-DBCC TRACEON (2610,-1)
-GO
-DBCC STACKDUMP with FILTERED_DUMP
-GO
-DBCC TRACEOFF (2610,-1)
-```
-
-Alternatively, you can add `-T2610` as a startup parameter to your SQL Server instance so it always creates compressed memory dumps.
-
-If you manually run Sqldumper.exe, you can use the `-zdmp` parameter to capture a compressed memory dump. For example:
-
-```cmd
-Sqldumper.exe <ProcessID> 0 0x8100 0 d:\temp -zdmp
-```
-
-You can also limit how many cores Sqldumper.exe can use to create the compressed dump by using the `-cpu:X` parameter, where _X_ is the number of CPUs. This parameter is only available when you manually run Sqldumper.exe from the command line:
-
-```cmd
-Sqldumper.exe <ProcessID> 0 0x8100 0 d:\temp -zdmp -cpu:8
-```

 ## Factors that prevent or delay creation of memory dumps
 
 The following factors are known to cause delays or prevent the creation of memory dumps.
