Hi all, Thanks for your prompt response.
My main intension of this scalability testing is to find out 1. how long it takes for the ntpd server to serve 100,000 clients. 2. What is the rate at which the server can process client requets. So, to test the above, I want to be able to simulate a 100,000 clients so i can hit my ntpd server with these 100,000 client requests. Please let me know if you have more questions. Thanks, RC. ________________________________ From: Chuck Swiger <cswi...@mac.com> To: R C <rc_w...@yahoo.com> Cc: questions@lists.ntp.org Sent: Sat, September 25, 2010 8:55:36 AM Subject: Re: [ntp:questions] Test ntpd performance On Sep 24, 2010, at 11:23 AM, R C wrote: > I want to test the performance of the ntpd server.

The ntpd sources come with ntpdate; use "ntpdate -q" in a shell script loop to issue many queries without changing the clock. Anyway, even on old Pentium-grade hardware and 100Mbs ethernet, you should be able to do thousands to tens of thousands of NTP packets per second. The bottleneck almost invariably will your upstream network connection, either in terms of bandwidth or in terms of a firewall/NAT box trying to keep state.
