    Hi!
    Disable services you don't need...or buy more RAM. I really don't see any other two ways about it. It's not using any swap..so..I don't see a problem here unless you plan on using this to sell hosting space.

    Don't get me started on this topic..it's not pretty. Do what you want.

    Hi!
    Sigh. Ok..let's try this again. This is normal.

    Normal.

    There is no problem.

    In fact..I would never *EVER* put Plesk on anything less than a 512MB vps with at least double that burst RAM.

    If you notice the total SWAP partition size is 0 That means that the container is either OpenVZ or Virtuozzo as neither of them support the use of SWAP.

    Plesk is definitely a RAM hungry control panel... I would consider switching to DirectAdmin as it is much less heavy on the RAM usage.

    You will have to figure out the best VPS optimization balance for running applications and your web traffic.
    Direct admin or LxAdmin, are lighter than Plesk and cPanel is tight on 256MB Ram, but can work. Look for options to take advantage of burstable Ram for more stability.

    thanks. My host doesn't uses swap. Divided with proxmox. They don't gives burstable ram.

    Plesk runs happily on a 160MB SLM memory VPS (virtuozzo); the majority of memory usage comes from extra services you might *optionally* run. The key, as already mentioned, is to remove the services you don't need such as mailman, spamassassin, dr web etc.

    Of course if you decide that one or more of those is important to you then you need to go ahead and provide enough memory to keep them running...

    This still sounds like high memory usage to me, though of course I'm used to memory requirements for our Virtuozzo based customers which tend to be a bit lower...

    Glad it's working better for you now anyway

    Well, Plesk requires allot of other services that eat RAM, like Apache, MySQL, etc.

    In linux its normal to see all the ram used or assigned to services.

    Still, I don't recommend you to use Plesk on anything less then 1 GB. I say this, because if you installed Plesk it means you will use it for hosting websites, and 512 RAM is nothing, when you start to use MySQL, Apache, Emails, etc.
