How good is the binary diff in Jazz SCM?
We are delivering binaries as part of our build and wanted to know how good the binary diff is in Jazz SCM. For instance, if I am checking in a zip file and all that changes are modified dates in the zip file (ie the build was compiling the exact same source as the previous build), how much of the new binary needs to be saved in the checkin compared to the original?
The reason I ask is that if jar/zip files are not handled efficiently I have the (second best) option of checking in expanded JAR files which would only need to commit individual changed classes rather than the whole jar/zip file. Then at deployment time, the class folder can be re-JAR'd.

If you have delta compression enabled then you should be getting very
high compression ratios if the only things that differ are the mod dates

Thanks Dmitry, but it seems I'd need to get my manager to pay for the
Standard edition as reports aren't included in the Express
edition.... :-)
I'll see if I can achieve the same test using a DB2 client.
