Spikes alternating between downloading and disk write

Post by Thor333 »

Hi,
I have a 150Tb, 400+ torrents, 6M files seedbox in a proxmox container. I made a JBOD with mergerFS for all my 11 disks.
I installed different transmission versions, from different sources (right now integrated in swizzin, but before bare), and i always have the same problem. (i installed rtorrent, seemed a little bit slower but no spikes at all, so probably not related to mergerFS...)
A picture is better than 100 words...

So, massive spikes between download, disk write and processor.
I changed many options, nothing worked.
Any advice?

HP DL380 g8, so i'm pretty sure my hardware can handle what it takes...
dpkg -l | grep transmission
ii transmission-cli 3.00-2.1+deb12u1 amd64 lightweight BitTorrent client (command line programs)
ii transmission-common 3.00-2.1+deb12u1 all lightweight BitTorrent client (common files)
ii transmission-daemon 3.00-2.1+deb12u1 amd64 lightweight BitTorrent client (daemon)


("preallocation": 1,"cache-size-mb": 32,"lazy-bitfield-enabled": false,"utp-enabled": true... Examples of what i changed, folder permissions...)
Thanks!
