    Alekseya, judging by your screenshots, you have only about 2.3 Gb of memory consumed by applications. This is not that bad.

    Here's what the numbers in top/free/Health monitor mean, if you need clarification.

    Total - your total (physical) RAM (excluding a small bit that the kernel permanently reserves for itself at startup).
    Used - total memory in use by OS.
    Free - memory not in use at all.

    Total = Used + Free.

    Buffers/Cached/Shared - this shows memory usage by OS itself for specific purposes. Values are included in the 'Used' value. This memory is usually used by OS to speed things up and can be claimed by applications on demand.

    Therefore to see "real" memory usage you should calculate (Used - (Buffers + Cached + Shared)). Alternatively call 'free' command, which does it for you in the '-/+ buffers/cache' output line.

    Also, it's worth to note that "MEM" field in 'top' output is "a task's currently used share of available physical memory" or a so called resident set size. "VIRT" or virtual image size is usually more representative in terms of overall memory consumption.
