many hdd read/write cycles slow down the system

kazu
i just got our new home-user astaro working and i'm very happy. but one thing:
i installed the astaro onto usb-stick (tmp / log mounted to tmpfs, syncing on boot/shutdown). 

why? less power consumption and smaller case for the hardware.

when surfing the internet, i get many write accesses to the stick (seems to be the /var/storage partition) slowing the system down dramatically (80% cpu cycles waiting for the usb stick). 

When shutting down the http-anti-virus, everything gets ultra-fast. Am i right, that before scanning for viruses, the website's content is stored to disk? if so, is there any way to scan the files in ram to unburden the usb stick? mounting /var/storage to ram seems exaggerated (currently 500 mb)

i don't want to change to internal hdd, if possible [;)]

thx for help [:)]

    Arminf, Snort doesn't write to disk (except for logging)

    Kazu, perhaps running a SATA and power cable to an external SSD would work for you.

    Keep in mind with your change to use tmpfs, if you download a very large file via HTTP, you will fill up all ram and crash the system.

    There's lots of http test scripts, but most are not as well documented as AB.
    perhaps look at some of these search results:
    http://www.google.com/search?q=squid+benchmark
    (astaro doesn't use squid anymore but the benchmarks should be standard http)
