Summary0001448: Message throughput dramatically dropped after upgrade to 2.8.9
DescriptionI just upgraded to version 2.8.9 after running 2.x.x successfully for months.

Before the upgrade, the old version of phplist would send out AT LEAST a couple hundred e-mails a time everytime I manually processed the queue (my distribution list is about 3000 e-mails long).

Now that I've upgraded, version 2.8.9 is only sending out approximately 50 e-mails at a time.

I thought this may have had something to do with me processing the queue manually, so I configured a CRON job to process my queue. The cron job is running every 10 minutes and phplist is still only sending out 50 e-mails at a time.

Batch processing is definitely off.
Additional InformationI was manually processing the queue using Internet Explorer on a PC as well as a Mac (latest versions).

Finally configured the CRON job and having the same problem.

Absolutely nothing else had changed with my host or my PHPlist configuration settings since I upgraded to 2.8.9.

I did add 1000 news e-mails to my list right before the upgrade to 2.8.9.
TagsNo tags attached.

few questions,
do you have your own machine (ie no ISP who has set batch limits)
what 2.x.x version did you run before?

I'm pretty sure I was running 2.6.4. I host the account off of powweb. Always have.

Powweb has a very active community support board. If this problem was a server config setting on their end, folks on the message boards would be screaming bloody murder. (

I just did a new mail out. The first since I posted my issue. I upgraded to phplist 2.8.10 and I'm having the exact same problem.

After the cron job fires, about 55 messages are processed. (but 1/2 the time, phplist doesn't send ANY messages).

I see a bunch of these in my eventlog:

"A process for this page is already running and it was still alive 1209 seconds ago"

If you have any suggestions I could try for you, or if you would like to look at my installation, send me e-mail.

messages that are "skipped" are messages that have been sent before. phplist avoid duplicating a message to a user, which is one of it's most important features, whihc is why it "skips" some messages. So all the "skipped" messages have actually been sent.

also, the main reason probably that things are slow is that you seem to be firing off the process queue process several times. Just the once, maybe repeated after an hour or so to make sure, should be fine. Don't keep clicking that "processqueue" link every single time. In order to avoid stalling your server phplist only allows one process at a time.

Do you have any comment on what could be the reason why I could hit processqueue on the 2.7.x versions and have 200+ mails go out at a time, but when I processqueue on the 2.8.x versions, I get 55 or less mails going out at a time?

I will modify my cron to fire every 60 minutes as opposed to every 15 minutes, but I'm worried that it will take ever longer to send to all my 4000 users. It took over 24 hours to complete this last mail.

I just downgraded to version 2.7.2 and phplist is once again blissfully sending 100's of e-mails each time I process the queue.

I see another user post in the forums experiencing the same problem I am since the batch processing stuff was added in the 2.8.x versions. They are using a different hosting company than I am, so it's not just me. Please review.
