I'm currently running an ISPConfig3 setup following on a Linode VPS with 1.5GB RAM, and it's working pretty good.
However, I'd like to optimise it with an aim of running it on a 1GB linode.
I only have about half a dozen websites with associated email accounts, etc. The websites are mainly Wordpress ones.
If I reboot the node and leave it for a few minutes to settle down, it takes about 1GB RAM, but this often rises to around 1.3 - 1.4GB in use.
Edit: current RAM usage:
Looking at the memory usage, the greediest one seems to be ClamAV running with Amavis-new for scanning email: they seem to eat up to around 400MB between them which seems rather excessivee to me!Code:Name Count CPU Memory amavis 3 0% 280 MB clamd 1 0% 245 MB apache2 11 0.01% 152 MB mysqld 1 0.14% 48 MB
So I'm trying to decide what my options are and would really appreciate your thoughts / recommendations.
Do I:
- Remove all av / amavis packages to free up the ram (but take a risk on virused an wormed emails?)
- Keep what I have but "tune" it. If so, are there many parameters to reduce RAM usage?
- Change from ClamAV to something else, if so which AV? BTW, ClamAV is currently running as the daemon (clamavd)
- Something else?
So any of you with experience running these kind of systems with some ideas?
Thanks in advance,
Xav
