So.. been a while and thought a update is in order as the performance thread to me has been interesting. Now on almost 10 years since first post on this thread.
Since my last update I had put an Intel optane 2tb nvme (1000 Mbs) in the computer in the old computer that has been referenced before. I am still using that system today. I put that drive in on an add on card about the time of my last post. And used it for a long time. though I don't have any hard data as I was happy and didn't think about it. it worked well and reasonably fast. I did want one of the 3500MBS nvme's but couldn't afford it. I got the one I did back there for about 1 dollar a TB.
However I have a new system gifted to me that is a 2nd gen ryzen 7 that a gamer friend retired and have moved my calibre library from the old system. When doing the move about 3 months ago I put in a 4tb crucial 3400 mbs NVME in the system as I had almost filled the prior 2TB drive.
I am running
Ryzen 7 2700x
AMD Vega 64 video card
32 Gigs Ram
Both cpu and video liquid cooled.
OS is Ubuntu 22.04
OS is on a 1TB samsung NVME on motherboard
Calibre drive is a Crucial 4TB drive in a Highpoint 4 nvme enclosure in a PCIE slot. Highpoint is old and im not running the drivers for it so am taking a bit of a performance hit using it.
here is link to drive. I paid just under 400 dollars 3 months ago.. they have it for 249 dollars right now.
https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
NVMe (PCIe Gen3 x4) technology with up to 3500MB/s sequential reads, random read/write 650K/700K IOPS
Spacious storage up to 4TB
Performs up to 33% better than the previous generation
Solid Gen3 performance
Rated at MTTF greater than 1.5 million hours for extended longevity and reliability
I would prefer latest gen 6500 mbs drive but cant afford that.
ok now that that is all said.
I have 315,000 books in calibre
the database metadata.db is 638.3MB
There are 71,446 folders in the root of the calibre files directory
It takes 18 seconds for calibre to start with that library selected.
with an empty library it takes 3 seconds
a search now takes 2 seconds on average
Linux does not like indexing and viewing the directory that the calibre books are in.
There are 71,446 folders in the root of the calibre files directory
there are 1,330,796 items (1.1 TB in size) in the directory and just to get a properties on it that show that takes about 20 minutes.
There is another directory for comics on drive that calibre isn't handling. with about 600 gigs in it.
Drive shows 2.1 TB free
The is a disparity between what shows in calibre
