Memory usuage after reboot
-
Yeah the memory usage might possibly be a related symptom but it's not a cause here.
It's almost certainly CPU usage causing those ping spikes. Check the system log like I suggested earlier. If some process is triggering it you should be able to see that firing when you see the ping issues.

I thought pfsense ran from ramdisk once loaded from ssd. If so then why would 50 percent lower memory usage not be a red flag. Its not cpu spikes as it has never been past 20 percent during high load and gui with monitors usually never see more than 1 to 6 percent. This could be hardware related, except if i get an update and it reboots memory usage will be 18 percent which is normal not 7 percent. My internet is 100 down 10 up, no way its stress a quad core at 3.8ghz without power savings of any kind or turbo , this cpu is not power or heat throttling. Its like pfsense cant load all of itself into the ramdisk after reboot

Please understand that this is a problem you and you alone are experiencing. It might take some time to determine what is peculiar in your environment. Especially on an internet forum from remote locations given little information.
It might just be that pfSense doesn't run well on your specific hardware.

No it won't if you haven't told it so. There was the old nanoBSD version, that was pre-configured to run with ramdisk support but that is old news and if you didn't set up the ramdisk under System > Adv. Settings it will not run on any kind of ramdisk at all.

Again, no ramdisk if not told so! Don't jump to conclusions that you haven't configured.

Now I'm confused. You told us above that after a reboot it only uses 7%, not 18% and that this is (in your opinion) the point why it runs "flaky" somehow. Now you say it reboots and is 18% not 7%? Huh?
In the end you have to give us much more to "debug" that non-problem if you want to have a conclusion or explanation. But without ANY data at all - that you were told to please post here - there's not much to say other than: it's your isolated case so please show us more details, logs etc. or live with it. Explanations for ups and downs of memory were already given in spades.

@JeGr Only time it uses 18 percent memory is when first install with no reboots, or after update. All reboots result in drop in memory to 7 percent. Yes I set up /var /tmp ramdisk also for 250mb each which equals 500mb yet memory usage is still 8 percent. Although /var default 3.4mb on install uses only 5 percent, just increasing the space /var grows to 8 percent of 250mb which is alot more considering no changes made to the install, no packages added, no tweaks, no qos , just default install. So if it set up a ram disk, why dont i see 500mb being used or reserved? And Im looking for help, not a forum that just looks to defend pfsense blindly. I like pfsense but it has issues also.

The RAM usage is almost certainly either unrelated or some side effect of whatever is actually causing the latency you're seeing IMO.
However to track down what is using it we need to see what's actually changing so maybe the first 20 lines or so fromtop aSsorted by RES in each condition.Steve

It has nothing to do with "defending" blindly. It just isn't an issue as you try to make it one. I don't see a problem with RAM going up and down. You do. And you try to construct a generic pfsense software problem from it besides Netgate staff telling you, it is not.
So if you have a problem with it besides the RAM up/down in your setup and installation - e.g. your point with pfsense being slow/laggy after reboot and not really responsive - then I'd describe and submit logs to that so we can try and help fixing that.
I like pfsense but it has issues also.
No one said otherwise or told you "the product is flawless". If it were, we'd not have patches and updates. But ranting on about a non issue (e.g. RAM) is pretty much useless if all you do is give an opinion about it but NO logs whatsoever so we could actually have a look at it. @Gertjan @stephenw10 and @Derelict already posted multiple hypothesis about the problem with the plea to give us something to work with. Yet all you do is rant on about memory issues instead of showing outputs from top, ps, etc. How about some help?

It is possible that this is some entirely new issue and this is first time we are seeing it reported.
However the memory usage or lack of it is only an indication of some change, it's not itself a problem. And it might be a completely unrelated change.
@abailey10 Do you know a specific build that was not affected by this? Can you test the RAM usage in that? Can you test a 2.5 snapshot?

Not to be misunderstood: I'm totally for debugging that. But then I'd like to see some actual data, logs and readings instead of accusations and ramblings and textblocks ;) As I said, give us some data to work with :)

Spam was here.

What has fixed it?
What are you running that only uses 50MB? That seems unlikely!
