AW: [opencms-dev] Un/locking performance

[Andreas Zahner]

Jozef,

I assume you are using OpenCms 5. In this version, the lock state of each
resource is stored in the database. So when you lock a folder with a lot of
subresources, all lock states are modified, which can take a while. I
suggest to use OpenCms 6 beta 2 where the locking is done in memory and
quite faster. A lot of other new features of OpenCms 6 improve the handling
of large websites also, e.g the explorer view has been rewritten for
performance reasons when managing a lot of resources, too.

Betreff: [opencms-dev] Un/locking performance

    Hello!

   We are currently building some huge website, with hundreds of 
directories and thousands of documents. It is new wersion of existing 
site, so we build a ZIP file (currently some 700MB) and then import it 
into CMS via Database Import.

   We encountered some performance problem when we need to unlock the 
structure before publishing. It takes some 8-10 minutes 
(Pentium4 at 2.8GHz, 1GB RAM), so even in case of so huge structure we 
suspect some performance imperfection in the code. Or do you have some 
other hint how to improve performance of this operation (JVM/DB 
configuration)? Database is MySQL 4.0 or 4.1 - no visible effect on 
performace.


   And from the user's point of view: After confirming unlock dialog 
there is no sign of activity (like during publishing) for a very long 
time. You can hack this by clicking on the directory tree in the left 
frame and refresh the file/directory list, then you can see the progress 
of unlocking. But this is an "advanced technique" and it is hard to get 
this idea for the common user.


   Thanks,

J.Ch.
