Best way to mimic the load we get normally.

[Greg P. <gr...@sl...>]

Hi all,

 

Wondering if anyone can give me some tips on the best way to mimic a
load that we see around peak time.  I'm trying to mimic the load we
would see if we had 1000 users perusing a few pages on our site.

 

I have a conf file with the following general section:

 

BATCH_NAME= 1k-clients

CLIENTS_NUM_MAX=1000

CLIENTS_NUM_START=5

CLIENTS_RAMPUP_INC=3

INTERFACE=eth2

NETMASK=32

IP_ADDR_MIN=192.168.1.189

IP_ADDR_MAX=192.168.1.189

IP_SHARED_NUM=1

CYCLES_NUM=-1

URLS_NUM=8

 

The urls are all configured like so:

URL=http://mydomain.com/firstpage.html

URL_SHORT_NAME="firstpage"

REQUEST_TYPE=GET

TIMER_URL_COMPLETION=0

TIMER_AFTER_URL_SLEEP=0-5000

 

... ect ...

 

And the command I'm running the test with is:

./curl-loader -f ./conf-examples/1k-clients.conf -v -u -t 2

 

So when I run the test sometimes it seems that it's sending the number
of client requests to each url at the same time, which for 8 URL entries
would equate to around 8000 requests per second once it hits the max.
What I'm trying to do is show a load of 1000 user's on the site at the
same time, clicking to a new page every few seconds.  Am I doing it
wrong?

 

Also, is it more realistic if I use the -r switch?

 

I appreciate any help or feedback on this.
