About the license and CPUs

[Brainlag]

Hello,

I am a little bit confused about the license system and processors/cores.

Currently the configuration of the box I intend to install LiteSpeed is:

[root@server2 ~]# cat /proc/cpuinfo

What license (1-2or4 CPU ) should I apply ?

Thank you in advance for your reply.

Brainlag,

Don't think in terms of how many CPU's/cores you have (they are the same to LSWS as far as I know) think about how many you want LSWS to "use". If, for example, you are running a heavy PHP/MySQL application you may only want a 2-CPU license. That then "logically" leaves 1/2 your CPU's/cores to run the PHP process and MySQL.

I hope that helps,

Frank

What Frank said is true, another thing to consider is the I/O wait, like all other light weight web servers, blocking disk I/O will block lshttpd process, so if your server has high I/O wait, you should consider license for higher CPU count in order to compensate and bring the best out.

I'm on a total newbie at servers. Someone has recommended me litespeed.

I have a Intel Core 2 Quad, so that means 4 cores right? So according to what ffiengol said, you don't have to actually purchase the 4 core package. Instead you can just purchase for php/mysql application? And all this can be set up easily by yourself?

Also is http stuff considered for 1 core?

[mistwang]

You are free to use 1-CPU, 2-CPU or 4-CPU license on your server.

[azn_romeo_4u]

Cool.

So for example. I have two websites. One is a pretty large and active forum, and another website that allows hotlinking of small 1kb-15kb files. Mainly in those range. Some files go over 100kb but rarely.

Would two core setup be good or should I just try the 4core?

Also on the trial version do you get to test the full version?

[mistwang]

You can choose between 2-CPU or 4-CPU license, if you I/O wait is higher than 10%, go with the 4-CPU license. You can upgrade to 4-CPU license later if need.
The trial license is a full 2-CPU license for 15 days.

I have a Dual core Xeon server,using 1 core cpu license of litespeed, holding 1350 low traffic domains. It work great with 1 cpu license.

The server load is always under 1 around all the day.

Thanks to litespeed.

I am still on my trial, is there any way I can use a 1-CPU license instead of 2 for the trial? The reason is because I can only afford the 1-CPU license and want to know how it performs on my server.

You can create a listener for the IP that your main site associated with. set "Binding" to one process only.
