As part of our 8.5.1 upgrade we hope to enable design and body compression when upgrading to ODS 51.
I’m seeing about 30% disk space recovery after enabling both on some archives. Has anyone seen any end user performance issues? Do documents appear to open slower? I know there are server performance gains due to less IO.
Any comments would be great
Subject: not really true
you will get 30% of savings in the body content, but not 30% savings in disk space. Also you should be aware that it will not compress attachments, only the body of the email (text and embedded images).
You said that you get performance benefits… in fact it’s known to be on the reverse: The server does the compression/decompression so each time you need to access the content the server will need to decompress it… for example if you have an online scanner in the server, then for each email sent/received the data must be decompressed… the same when you access it from DWA.
Atts represents 90% of the email storage… so you would generate a saving of 30% in the remaining 10%!
If you really want to save disk space, you should compress attachments by replacing them with .zip files since it’s by far better than LZ1. There are some third party products doing this, the best known in the industry is ZipMail (www.mk-net-work.com).
