I completely understand that many factors can affect throughput, but I'd just like to find out if I'm in the correct ballpark, or if I have some problems that need to be addressed.
When my outbound spool gets full and is running full-throttle sending outbound emails as fast as it can, according to the log files, I'm averaging about 5 emails going out every minute. This works out to about 10 seconds per email. I'm not even close to being network bound. I'm on a co-lo server with a major provider. My network adapter isn't showing anywhere near capacity. My processor is running at 4-5%. So I'm assuming all of the time is spent in contacting remote servers and establishing the connection to send the email. Does it really take that long per email? Just wondering if, in the interest of curbing spam, my co-lo provider is possibly throttling back on port 25 or purposely inserting delays. I've heard of DSL and cable providers doing that for home users. But hopefully not a business co-lo provider.. Or is it possible that the target servers are inserting delays? It seems that "outblaze.com" almost always takes 8-10 minutes to send to. Anyway, could you tell me if averaging 5 emails per minute running full throttle is pretty much the norm, or is this seriously low? Jerry
