Re^3: Mail::SendMail and fork

fork is a bad idea on Windows, and it's a bad idea on any system to try to fork 10000 processes at once. Take a look at Parallel::ForkManager or a simple thread-based solution that runs (say) 5 or 10 worker threads and feeds them from a queue.

Thanks! I suppose ForkManager is also uses Fork function, not sure. Basically I'm testing Mail scalability, it would be good if I can stress the server with 50000 mails per day sending mails in parallel...	[reply]

Even using threads, those sorts of numbers will cause tremendous context switching issues. 50000 mails per day is not the same as 50000 all at once. If a mail takes one second in the system, 50000 is only two per second if evenly distributed throughout the day (which it won't be, I know). What is your peak?	[reply]

It is like this Users 9000 Mail box 9000 mail/box 2000 Total mails per year--- 18000000 Per Day 49315.06849 = (18000000/365) Uniform Distribution/sec 1.712328767 (ie mail per sec)	[reply]
