Running Harvest SCM on SUSE Linux with Oracle Database on the same Linux server.
After upgrading the SUSE Linux OS from SLES 11 to SLES 12 SP3, the local checkouts are taking a very long time.
A checkout of a 11 GB item on the Server took 11 hours. Before it was taking minutes.
The checkout of these 11 GB on Windows only took half an hour.
The MTU size for the loopback interface was changed from 16436 in SLES 11 to 65536 in SLES 12.
Harvest SCM 13.x
After changing this size back on the servers, Harvest is running on and local checkouts now run as fast as before.
