May 24, 20179 yr Fix Common Problems is giving me this error. When I transfer files to the server the speeds sometimes goes as low as 1MBps and then up to 70MBps after a few minutes. deusvult-diagnostics-20170524-1240.zip
May 24, 20179 yr They are all page allocation stalls ie: The computer is having a brain fart... Looked like they happened around 4:04pm your time. You can try to install the swap file plugin which may eliminate / limit the impact that this has on your system.
May 24, 20179 yr Author What does that mean? Is it fixable or a permanent issue, never had this before. A swap file shouldn't be necessary? I have 128GB of RAM.. Edited May 24, 20179 yr by kakmoster
May 24, 20179 yr I honestly don't know... Multiple page allocation stalls averaging ~14 seconds. Maybe your NIC (Realtek?) was consuming all of the CPU resources at the time which led to it and the slowdown in the transfers...
May 24, 20179 yr Author Hm, can it be to hot? It's quite hot atm and I think the NIC is at above 60 degrees? I have dual xeon E5 2670, cpu resources shouldn't be a problem? Gonna check for a bios update, do you think it might help?
May 24, 20179 yr Community Expert Try installing the Tips and Tweaks Plugin and considerably lower both RAM cache related settings: Defaults are to high for systems with large amounts of RAM, and it can cause the OOM errors.

Thanks!

May 24, 20179 yr Community Expert vm.dirty_background_ratio and vm.dirty_ratio, default is 10 and 20, start by setting them to 1 and 2, if stable for some time increase them a little, up to 5 and 10. Edited May 24, 20179 yr by johnnie.black

Okey, does this only apply if I use VMs? I don't use any VMs at the moment. However I'll try it and come back with results

Why does it cache so much?? It's better than before, it doesn't stop completely, but it does drop a lot.. deusvult-diagnostics-20170524-2033.zip Edited May 24, 20179 yr by kakmoster

Sometimes transferspeed drops to ~10MBps, I believe it averages somewhere around 40MBps. Much better, but still worse than I've had before. Does it matter if the share I transfer to is set to High-Water, Fill-up or Most-Free?
May 24, 20179 yr Author 1 minute ago, johnnie.black said: Most free can be slower because parity writes overlap. Okey, that might be the problem then. Gonna change that.
