I am not sure when exactly this started, or what caused it but recently navigating my WebUI has been extremely painful. I am seeing page load times of upwards of a minute or more. I had not needed to log in for multiple weeks, and made no real configuration changes. Wondering if anyone can point me in some form of a direction here. I tried rebooting, to no avail.

 

I actually had logged in to increase my docker image, clean a few things up and see how things had been. It was slow before touching the docker image, I had just chalked it up to nothing initially, but every page I try and load is consistently extremely slow. Previously, the pages loaded quite fast!

 

Diagnostics attached...

haha oops, had been a while!

Bumping this, as I have still been unable to find the source of the WEB UI slowdown. It is so slow I can hardly even configure anything additional in my server.

 

I have tried shutting down all VM's, all dockers, rebooted server and I am still getting minute plus page loads on the system. I can copy files to and from the flash drive with decent speeds, 30MB/s, which is as fast as it was when I brought the system online.

 

Anyone have any ideas?

A time ago, I had a bad drive which caused the UI to go stupid for a while.

 

I knew that the disk is broken, just had no Linux around and so I used Unraid to get me some error messages about the drive. Loading time of the array screen was about 2-5 Minutes. It probably? is another Problem, but it could rarely be that one of your drives just has some Issues. This is especially the case if it is not an read error on the platters.

 

If possible, you could Check if the problems occur without any drives being attached. Take note, that the non array related UI was lagging behind in that situation also.

 

Glad if I could help, keep us updated - I'l probably send you some questions about your setup soon, as I probably try to copy it.

Thanks for the details, I had not even considered that. I will give it a look when home this afternoon.

I've carefully examined everything from that earlier diagnostics, and all drives look fine, and the whole system looks fine!  I see no reasons at all for slowness.  Not everything is visible in the diags though.  You have 4 VM's going, all quite active, are you sure they are pinned to separate CPU's, and leaving CPU 0 alone for unRAID's use?

 

As far as I can tell, and you don't mention anything otherwise, the system looks fine, only your browser experience is suffering.  You mentioned that flash drive I/O is normal, how about other I/O, such as transfers to and from the array?  What I'm trying to confirm is if the issue is with the server, or with the browser or the networking between you.  Have you tried on another machine to access your unRAID server?

Are you using Workgroup or Active Directory?

I tried the server with:

 

1. All VM's off, dockers off, array online, still very long to respond(webui)

2. All VM's off, dockers off, array offline, still very long to respond(webui)

 

Accessed from multiple computers, chrome, ie, phone, VM within the server, all icnredibly unresponsive. I turned off my link aggregation, switched ports on my switch, switched cables, upgraded to the new RC, all no dice.

 

I swapped USB ports on the server and noticed on reboot the server didn't want to recognize the USB drive. Popped it back to original spot, no recognition at boot, powered down server left down for a few moments unplugged and powered back on and drive was recognized and server booted. However, still very slow webUI. All else loaded fast, server came online fast, transfers to/from flash drive over network at ~30MB/s.

 

I will investigate the USB issue tomorrow once I am back around the house.

Your server still looks fine to me.  Still think the issue is with your desktops or the network.

 

On your server, the workgroup is set to "WORKGROUP".  Does that match what you have your desktop machines set to?

And does browsing to the IP address instead of the name make any difference

My desktops are all indeed "WORKGROUP".

 

Browsing to server name or the IP had same affect.

 

Now, interestingly after removing the IPMI plugin, turning off the server, removing the USB drive and replugging it, turning the server back on, all is snappy as ever. I do not know if it was related to the IPMI or the USB, as I definitely seem to be having USB issues on the motherboard. My UPS connection is being flakey.

 

Thanks for all the help and pointers everyone.

 

Please let me know if anyone would like me to reinstall the IPMI tool and see if things go wonky again, or leave updated diags, in case anyone is curious to exactly what was happening.

An incredibly interesting update:

 

Since removing IPMI plugin, my system maintains many GB of free RAM. Before, I would always have ~30-35GB used, and the rest cached, with only a couple hundred "free". Now I have anywhere from 5-15GB free at a time.
