This is a long-standing problem that we’d like to get into the support branches. While the problem affects performance of transmission of large messages it also causes decryption problems with secure communications using TLSv1.3. While folks can avoid the problem by using TLSv1.2 we would like everyone to be able to use the most up-to-date security algorithm.
The fix is isolated to the communications BufferPool class and its unit tests. https://issues.apache.org/jira/browse/GEODE-8506
