Why don't you set up a test on your own and publish the results.
It should be relatively straighforward:
- Generate let's say 100'000 objects.
- Store them
- Retrieve them
--> at random
--> in sequence
-let the test run for some time (e.g. a day)
-collect statistical data and measure the time.
-publish the results
Looking up what's written about Minnestore prompted to ask:
Where is the current place of minnestore?
Swiki page http://minnow.cc.gatech.edu/squeak/1051
mentions that the URL below is the current one:
http://minnestore.sourceforge.net/index.html
But this has a copyright notice of 1999 and the implementation is for
Squeak version 2.7.
Is there really no newer version?
What I would like to have for my work is a persistence mechanism which
is totally transparent for the user. I would like to see just one large
image (say 500MB) and work in a 64MB RAM machine. The underlying
mechanism would take care of swapping in and out objects.
I am aware of the the solution using ImageSegments
(http://minnow.cc.gatech.edu/squeak/2316) associated to projects. But
there the swapping is synchroniszed with project entering and leaving
which is fine in many cases.
