strongly need your hints for speeding up server!

  1. We have a 1 or 2mb server on our university without any firewall or any other protector or speed up app. and another 2 servers for dial up users and network and both are same they told me to fix them up cause thay seems to be slower than what they are specially dial up server. the network server have less users with very low use at max attaching files for some mails (heaviest work the do sometimes).
    I want to know what I how I could do better? example: I were thinking about zone alarm it give me full protection and it's fast is that good or there's something better I don't know?
    any qusetions or info needed plz ask?

    What version of Windows do they run? If you are running a server version such as Windows Server 2003, then you have to get a compatible Antivirus. From the likes of PC Cillin and Norton for example.

    If the systems are slow, adding ANY Antivirus/firewall program is just going to slow it down more. But it's a necessary evil I'm afraid.

    Of course the best way to speed up a system (hardware wise), is to add more RAM, faster CPU and faster hard drive.
    Use Task Manager to see what your RAM usage is like. And can you post some hardware specs of the slowest one?

    If you are afraid of being infected with bugs, run Adaware and Spybot, and run an online virus scan from www.bitdefender.com. All free to do.
    You can also make sure your startups are clean, and have as little of programs running as needed. Also keep your file-serving machines defragged.
    Make sure all the servers have a good sized page file set.

    On the dedicated servers, such as the dialup servers, you can use Task Manager to raise the priority of the server processes. This will tell the system to spend more time processing from that program, which can help speed up that service.

    I would recommend running a registry cleaner such as CCleaner

    Ccleaner doesn't really clean the registry, it cleans temp files all over the hard drive. But yes, it can help speed things up.
    Registry cleaners are like Regsupreme and WinDoctor, which deal specifically with the Windows registry.

    please post more machine specs and the OS yer running
    routers used and or switchs used
    looking for firewall for uni go with a boxed firmware system
    that does not use the servers cpu / memory
    if its a good uni they can afford such
    example barracuda IM firewall

    PS linux is faster my 2 cents

    ok.
    i ask for more sys specs.
    but is there any special speed up program?

    manual caching and memory allocation
    for server I would not depend on or take a chance on a program that says it will speed up the way your server handles clients
    again without the type of machine and OS can't tell you much
    can say you want fast through put you need gigbit network or fiber optics in place
    dealing with larger systems try cisco website very good articles on managing networks
    when I ran my apache on W2K one thing I did was enable Gzip to send data compressed
    the clients system automatic uncompress's
    if running a W2003 server I can't help I never bothered with it
    this is a very big topic with diff layers of fields that need to be addressed


    good luck

    Samstoned is on track here.

    Primary performance is governed by:
    1. cpu speed
    2. installed memory
    3. i/o system performance
    Memory and the I/O system interact when paging becomes a factor.
    Paging, especially for servers, can get excessive when there are too many
    processes active on one system AND the access from the clients starts rising.

    typical means to improve server performance include:
    • installing memory
    • using dedicated devices for paging
    • limiting concurrent threads
    • removing non-esential processes / services

    You need to get some performance numbers to determine what the
    PROBLEM is before you over react with changes that may not have any influence on the outcome.

    server specs

    os:
    linux squid
    client manager: nttack plus

    imo, accelerator programs are to performance gains as adjusting the tire pressure on your car -- yea, getting it right will be an assistance but not nearly as so as a good tune-up or a replacement engine.

    why pay for or be concerned about a 1% improvement when you can get 20-30% by proper systems configuration and management?

    Samstoned nail the requirements:
    ... again without the type of machine and OS can't tell you much ...

    meanwhile, read-up on performance monitoring

    Not even iptables?

    Can you be more specific about "seem to be slower than what they are" ? What are they, then?

    Check that there are no unnecessary daemons / applications running, optimize the kernel, check its networking, virtual memory and file caching settings.

    There's no ZoneAlarm for Linux.

    speed up your web server

    still no software that I know that does it all
    thats like optimizers for browsing they don't work
    if your IT you can get system logging software to help you find the bottlenecks

    good luck

    Linux Performance Monitoring

    you might start with this website


    xinetd: controls services which are auto started
    the control list is typically located at /etc/xinetd.conf
    and depending upon which specific Linux you're running
    may have other files in the suibdir /etc/xinitd.d/*

    XINETD is the first place to start reducing workload.
    you should know WHY each and every service is made active and
    WHY you need it. If it's just 'it would be nice ...' make it
    disabled! set ONLY the processes you need, disable the rest,
    and send KILL -1 $pid-xinet.d-process to reconfigure the
    running system w/o a reboot.

    now the quesiton becomes, what's chewing up the resources?

    System Load: use uptime
    the last three numbers are important. see man uptime(1)
    load average should be no more that 3, better still 2 or lower
    only two soultions here: add more memory OR reduce process/thread counts

    Monitor Paging / Virtual Memory
    a combination pipe:
    watch -n 1 -d free

    actual Pagefile info is seen
    swapon -s​

    Linux Paging: man vmstat(1) which gives you
    DETAILS on swap in/out
    swap-out occurs for hi memory usage, dirty pages and
    the need to switch to another process. this will later
    generate a corresponding swap-in

    swap-in can occur for just simple page stealling
    (ie, not dirty and memory needed elsewhere)​

    Processes of course: PS
    you find HOW MAN and WHICH ONES are using the cpu but

    but here's the winner! TOP
    man top(1) will give you a better snapshot including
    uptime
    processes
    cpu usage
    memory usage
    swap space usage (need vmstat 1 for swap i/o)​

    Network monitoring? ouch! there's a ton of stuff
    google 'linux monitor network performance'
