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 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

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 ?
Best regards, Christophe

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
