really slow read times
-
ok so i just got done plotting my 4th 5tb external 3.0 usb hard drive and i was scanning all my drives in under a minute, now that im running my 4th external (plotted with xplotter, the others were all plotted with the burst client wallet) the read time has jumped to 137s. also all of these drives are plugged into 1 usb 3.0 hub, would that be the problem, all the drives being plugged into 1 hub? also should i just bite the bullet and start replotting my other drives with xplotter? do it now rather than later? order another usb 3.0 hub and split the externals up? any help would be greatly appreciated :)

I have four 4TB drives in a single USB3.0 hub with no slowdowns (20 seconds to read all drives), so I doubt it's the bus. I'm not familiar with xplotter, but if the plots are not optimized, that could cause slower read speeds. You could rewrite them, or you can use plot optimizer to optimize them, assuming that's the issue:

@sevencardz xplotter writes them pre optimized apparently from what ive read. so i have 4 un-optimized plots and 1 optimized plot, but before this newest hard drive i was reading 16tb of plots in like 30-40 sec, now 130ish seconds? doesnt seem right lol

I have 55TB on one USB 3.0. The last plot comes in at about 65 seconds.

@rds right now I have a 17 Tb on one hub but the 8 Tb drive completely scans in about 37.2 s, while the 4 Tb finally finishes at about 50 s. Not really sure what the difference could be...

My setup has 4-8TB drives and 8-4TB drives. Each 8TB drive is partitioned as 2-4TB drives. The 8TB drives have their own power, the 4TB drives are hub powered. I have 2-7 port, powered USB 3.0 hubs feeding into a 4 port unpowered hub connecting to a laptop. My total scan rate at the bottom is usually ~200MB/sec and the individual drives are ~12MB/sec.

@rds said in really slow read times:
Each 8TB drive is partitioned as 2-4TB drives
when miner reads plots from one drive splitted by few partitions - it make many seeks for reading. better use 1 partition

@elesdii If you use jminer, please read here, i made a bugfix to solve speed issue:

im cpu mining and plotting (with the burst wallet), but i just cant seem to figure it out with what little spare time i do have when im not sleeping or working. i should only be working 8 hrs tomorrow hopefully not 12 again like all last week. im rocking an i7-3770 3.4GHz and a gtx970 but i just havnt had the time to try and figure out how to plot/mine with my gpu.
