Seafile RAM usage in a VPS

I’m planning to use Seafile (PRO version for 3 users) in a small VPS but with decent storage (128MB RAM, 40GB storage).

Does anybody have any experience running Seafile in such a low memory enviroment.

Most probably I will be running besides the seafile server the following services: openvpn, icecast, mumble, nginx (for static files mostly and same basic php pages).

Any comments on the plan?

I have Seafile running on a VPS with 1GB RAM and this is somehow the minumum I would use. Seafile alone uses around 500 MB RAM and I am the only user. 40 GB is not so much either, you will be surpised how fast it will fill up
