    You can start a trial license (2 CPU equivalent) and upgrade later if needed.

    Attention to this details do you think 1 LiteSpeed license is Enough for our server or we should Order More License ?

    With ordering more Licenses our problem will be fix or not ?

    This OverLoad is Due LiteSpeed or Another THing?


    Thanks for your HELP

    There is a known kernel bottle neck trigger by LiteSpeed when CPU/core count is very high. We are working on a solution now.
    In the mean time, you should turn off "AIO" under server->"tuning" tab from LSWS console see if it help or not.

    Hello

    Thank you for your reply

    we are using 4.0.20 version that not support AIO . This is a Bug from Litespeed that should be fixed . do you think when you could fix this issue?

    Thank you

    If AIO is not involved, it could be something else.

    Please contact bug@litespeed... if you would like to have our staff to take a look at your server.

    I had a question regarding this.

    My CPU is a Intel Core i3-2100 Processor, it only has 2 cores but 4 threads.
    If i purchase a 1 CPU license will Litespeed use 2 threads or as far as Litespeed is concerned i have 4 cores ?

    run 'top -c' etc to figure out what consume the most server resources and what is the bottleneck. if lsws takes most cpu cycles, you may try with a higher license.

    Atm i use 2 cpu license. when i typed that, i got the result below
    Code:
    avg-cpu:  %user   %nice %system %iowait  %steal   %idle
              37.45    0.05    2.76    0.29    0.00   59.45
    Should i use 4 cpu license now?

    p.m me i can configure your server better than old in same server
  17. webizen

    webizen New Member

    do 'top -c' and see which processes consume most cpu cycles. if it is 'litespeed', then upgrade makes sense.

    does your trial license still get deleted every time you try to start lsws? pm your server temporary root ssh access for me to take a look if so.
