Default value of the threadpoolsize agent affects batch indexing
Valid from Pega Version 8.5.2
After you patch Pega Platform to version 8.5.2 or higher, the system changes the default value of the threadpoolsize agent, which controls the number of concurrent activities (threads) in the system, from 5 to 15. Batch indexing in Pega Platform™ does not require all 15 threads, so you can change the agent value to increase system performance by managing the indexing/distributed/batch/numworkers dynamic system setting.
If your deployment does not support that setting, and batch indexing does not use Queue Processors, the system uses the threadpoolsize value for batch indexing instead.

BIX performance improvements for CSV output in the Pega Cloud
Valid from Pega Version 7.2.1
BIX performance has been enhanced to download up to 25 GB of data per hour for extracts from a BLOB-less class table for CSV output. This high-throughput option is available only for Pega Cloud instances that use a Postgres database. This option is used automatically for these types of extracts.
When this option is used, the –x and –c command-line options for BIX are not supported, and the checkSum field in the manifest summary is not populated. If you need these options, you can revert to the previous implementation by using a setting in the prconfig.xml file.
For more information, see BIX high-throughput data downloads in the Pega Cloud.
