I built a freenas from a old computer
Everything seems to be working and I'm still testing and playing with everything before i finish it up. Just to play with speed I striped 8 - 16tb drives together but when i goto do a speed test i get a burst at 730 MB/s write but then drops to an average of 320 MB/s and then Read average 438 MB/s. It looks like my 8gb ram was holding me back and i uped it to 16gb which is the max of my mobo. but still having bottleneck issues.
So im trying a 1tb sata ssd and recreated the pool with the ssd as a cache. I didnt see much of a difference. I was reading that the freenas default settings were not ideal for ssd caches. Is there a guide/tutorial on how to configure the freenas settings to utilize the ssd properly?
here is a video where i saw someone talking about optimizing freenas to use the ssd but looks like an older version of freenas https://www.youtube.com/watch?v=oDbGj4YJXDw&t=1s
Anyone configure caches using a ssd either pci or sata? what did you do and preferably why so i can try to wrap my head around it?
Thanks ahead of time
