Hey content, going forward, when its slow, can you make a record of the # of users on it, id be interested in knowing if there is anything there....
maybe the # of users in the evening goes way up and an additional server would help
The number of users is definitely higher than average in the evening, but I don't think that's the issue here. As I've mentioned, the load on the servers is pretty low; I think there's something else at play here.
I'll definitely keep that in mind though as I look into the issue.
There were definitely some issues on Monday. For some reason or another, it's a night we've had slowness issues for the last few weeks. My guess is that it's Monday night football related, and peoples' fantasy weeks are finishing up so there is a higher number of posts than the rest of the week. In any case, and for whatever reason, the performance of the site hasn't been acceptable, even after the upgrades.
I've been watching the server loads closely since the upgrades and noticed on major anomaly on one of the servers since the upgrade, and traced that anomaly to the fact that the server was a very old one that we weren't supposed to have after the upgrade. Since Monday this server has also been replaced with one of the higher performance servers.
I'm still waiting to see how we do on Monday before I consider things to be "stable", but I'm hopeful that after that correction things will be a lot better.
Thanks for the input though, without people letting me know, it's hard to tell what effect the changes I've made have had.
no problem. I'll admit, it is really frustrating when it's slow. but i know you are working on fixing the issue, and that's awesome.
Excellent. I'm fairly confident that the reason the site slowed down this evening was because we had the highest number of people on the site since we had all the new servers in operation and it hit the maximum number of active requests we could handle at a time (450). I've increased this number to 750.
Adding another server would increase this number to 1000, but the servers are still not at capacity, so we could push them a quite a bit further by pumping up some other settings; it's not "recommended" by default, but our servers are actually quite a bit better than is expected "by default", so that's the next step if we run into slow-down issues again.
 It should be noted that active connections is not the same thing as number of users on the site at a time - we could have 5000 users online, but some would be reading posts, some would be refreshing the page, and some would be posting. "Active" means hitting the server - this means refreshing/clicking links/posting.
