Subject: POSTGRES Append Performance
Date: Thu, 12 Jan 1995 14:07:47 -0500 (EST)
Message-ID: <199501121907.OAA07712@robin.mcnc.org.mcnc.org> (raw)

Hello,

	I am evaluating version 4.2 of POSTGRES as a database tool to
provide persistent storage of directed graphs.  The test program adds
one node which requires 17 append operations against an empty database.
Each instance has less than 100 bytes.  The program takes 10 seconds
elapsed time to execute.  Adding ten nodes takes 20 seconds.  Is this
"normal" performance for POSTGRES?  Does anyone have any suggestions to
improve performance? Is anyone using POSTGRES to support interactive
applications.

	The program is run on a SPARC10 workstation with SunOS 5.3.
The database resides on the workstation.

Thanks.

Ted
