Hi!
Kindly ask you to solve some unclear topics:
I. How can I find information about such dependencies:
- How many server RAM memory is required for each 1GB of attachments?
It depends on how large the attachments are. Currently (as of version 2.6) attachments are
stored on
the disk and in the database rather than in RAM so the only limit on the total of all
attachments is
the amount of space which your database can hold. Remember that the default database HSQL
holds all
tables in RAM.
If you're asking about a single very large attachment. There is some inefficient code
in the
attachment version storage which means that you can only store attachments up to about
60MB with
512MB of heap space (RAM). This can be bypassed by setting the attachment version store
type to
"void" and the limit will rise over 100MB where the problem will become the
transfer to and from the
database.
- The same for CPU.
The CPU usage for attachments is not really a factor as compared to the number of users,
page loads
per second, number of pages, complexity of queries etc.
How to estimate this and calculate hardware? What are
main principles?
It is an art as much as it is a science ;)
Others know much more than me about the rest of your questions so I will leave this to
them.

II. Is it possible to customise WYSIWYG editor separetly for each space in one sub-XWiki
?
III. Is there any way to manage anchors from Links plugin in WYSIWYG editor?
The logic is:
- select space
- select page
- select anchor on this page
- put the link
For now, even if I write down XWiki.WebHome#anchor in the link field manually, I get
#anchor cut out.
And the only way to do it via source code editor manually. Then it works fine. Personally
me found more or less suitable solution with FF plugin
https://addons.mozilla.org/ru/firefox/addon/416/
It's very easy to get anchor, but not so easy to put it. For unqualified users it
makes XWiki "one-handed".
IV. Is there any way to make TOC macro to build table of contents of several pages and
put it on one page?
For Example:
toc Page1, Page2, Page3 ....
It's very useful, when one can group all project highligts together in one TOC.
I used to use Track Wiki, it works excellent in there. I suffer from it's absence now
:-)
Thank you
