SQL Developer is Very Slow Downloading Full Distribution File to a Network Drive (Doc ID 2242351.1)

Last updated on MAY 02, 2017

Applies to:

Oracle SQL Developer - Version 4.1.1 to 4.1.5 [Release 4]
Information in this document applies to any platform.
SQL Developer 4.1.x
Database 11.2.0.4.0

Symptoms

Given you have a table with a BLOB field where the BLOB contains a .ZIP file, usually about 15MB.
Run a query in SQL Developer to isolate a single record and download the ZIP file for that record.

When saving to a local drive, the download completes in a couple seconds.
When saving to a network share, it takes 20-30 minutes.

There is no unusual network traffic to explain the dramatic increase in time.
