About the license and CPUs

[anewday]

Will this work if I import apache config? Please provide some detailed instructions.

George, this doesn't seem to work if I config lsws to use httpd.conf. Do I need to map virtual hosts? Virtual hosts are empty due to using httpd.conf.

Just create a listener with the IP for your main site. that's it.

mistwang,

What is the difference between the VPS license and the 1 CPU license other then the obvious that one is designed for a single CPU server and the other for a VPS. I have read that VPS license is basically the same as the 1 CPU license. I have multiple VPS's I am wondering if I should run the VPS license or the single CPU license to get the best performance.

http://www.litespeedtech.com/litespe...-editions.html I believe it's the same as a 1-CPU Enterprise version but limited to 500 concurrent connections.

ffeingol,

Many thanks for your help.

we host around 750 domains and our average load is 2 ! Can you please advice as on the best license we need to buy ? how can we find the I/O wait time ?

Thank you again for your kind support.

Best Regards,
Alexandros .

mpstat -P ALL 1
it will tell you your I/O wait for each CPU cores

if you host large static files and you see high IOWAIT values then you may try 2 or 4 CPU license but for high loaded PHP scripts an opcode cacher such as xcache would boosts your scripts and it seems enough to me with 1-CPU license but Mistwang can advice you better than me

IOWAIT is the killer.... it is why we went to RAID 10 with 12 15K SAS drives... we increased our IO performance 5x over a 4 disc RAID 10 array (also 15k drives).

In my humble opinion, processor speeds almost make no difference... the key to a fast site (in addition to something like Litespeed) is minimum IOWAIT. It seems to be the major variable that affects web performance.

Anything to reduce IOWAIT is worth it.

Warm regards.
