Re: [basex-talk] Sizing BaseX Server

2015-12-01 Thread Dirk Kirsten 
Hello Christophe,

that's easy: The more you got, the better it is ;)

More serious: It is hard, if not impossible, to tell. This very much
depends on your use case and how you intend to use BaseX in your
process. As a traditional database and having lots of read/write access,
you are most likely I/O bound. However, you can also do complex
operations using XQuery, so you could be CPU bound.

I find it almost always beneficial to use SSDs instead of traditional
HDDs, but again: If you never touch the disk at all, this wouldn't make
a difference (but it also decreases the BaseX startup time, which is nice).

The use cases just differs to much for BaseX - you can use BaseX
embedded into your smartphone application or on a large zServer, so it
is really though to give a general advice. For a practicable approach I
would always recommend you run your application at some standard server
and take a look using Java profiling where BaseX is bound and then
increase the according component.

Cheers
Dirk

Re: [basex-talk] Sizing BaseX Server

Hello Christophe,

I would see having a virtual machine as a big plus, not a negative. So
in case you really see a bottleneck you could simply demand more CPU,
RAM or whatever from your hosting provider and it will be a matter of
clicks instead of actually changing your hardware.

Cheers
Dirk

Ok, thanks a lot, Dirk. I had the same feeling, SSD, lot of RAM, big 
procs, etc...


The problem I have is the server will be a virtual machine, and I have 
to give sizing infos to infra to let them provision VMs...


Thanks again,
Christophe

Hello,

I'm looking at documentation about sizing a basex server computer.
What's best : kind of processor, number of cores, RAM, disk-system,
according to database size.

Is there something in documentation on these subjects ?
