As of GM 220.127.116.11 GoldSync has changed so that the Diagnostic Logging is on by default. This can have a huge impact on the times it takes to perform a linked document synch.
It is important that you add the following setting to the GM.ini on all machines that use sync.
The default value for GoldSync is 0
0 means that the files would be compressed separately – SLOW
1 means that all the files would be compressed together – FAST
