Why is it slow on Windows? (please apologize if I might have missed that explanation somehow)
and how is it on UNIX/Linux?


I did some tests on Windows, and posted results a few months ago in this list. Basically the main problem is that NTFS directory creation operations are really slow (I'm guessing it's the journalling that's interfering here). I must also say that I was creating something like over 10'000 files in my tests.


Does anyone have any actual figures (especially compared with CQFS)?

I don't have figure against CQFS but I do have some against Object serialization and my ORM persistence managers. The results are a bit dated now but they should be indicative of the problem of slow file creation under Windows.


You can find the results of my tests here :

Please note these are not very scientific, I was mostly trying to check if my ORM persistence managers where performing decently than actually trying to spend a lot of time on testing procedures.

 Serge Huber.
