If you use the default mode MDB_SYNC then it's reliable but can be slow for writes. For max write performance you need MDB_NOSYNC (IIRC that's what the official benchmarks use) but then the whole database can be unrecoverable in case of crash. It has happened to me.

Sqlite in WAL mode will never lose all your data and performance can be configured vs durability by setting pragma synchronous to full or normal.

So each enclosure hosts its own RAIDZ2. Have you tested if it can survive loss of USB connectivity? It can happen because of cable damage or movement, and also because of any failure in the enclosure's electronics.

Each drive shows up as an external USB mass storage device?

What is the systemd equivalent for `service crond stop` and later `service crond start`?

In other words, I want to disable all jobs for some time (for benchmarking) and then bring them back up.

  > The DC-ROMA RISC-V Pad II starts at $149 for the 4GB RAM version and is already available for pre-order on the DeepComputing store. 
  > If you get the 16GB RAM variant, the tab is compatible with the Android Open-Source Project (AOSP) Android 15 operating system.
Weird, isn't 4GB RAM enough for Android 15? Or is AOSP compatibility completely separate from Android compatibility?

Who are the phone/tablet manufacturers that are friendliest to rooting or installing open-source Android clones? It's a pain to do that on my Samsung Galaxy devices...

I'm looking to buy a (new) 10'' tablet for that purpose.

It's not the same buying a new product from official supplier, to buying something old and/or used from an unknown entity on eBay.

> bloat their io buffer size to several GiB, set the eviction priority to 1

How do you tweak these? I'm aware of dirty_writeback_centisecs and the likes, but you are most likely referring to something different.

> after paying more money than it would cost to buy a basic laptop

No need to be imprecise, unless you are trying to push some agenda. The cost is CHF 198, which is around USD 195.

They are only slow to compress. They are as fast to decompress, or even faster sometimes. Source: I tested.

JGit has advanced a lot, and is in use in software handling huge repositories like Gerrit code review system. Java has also had numerous advancements in the past 10 years.

It would be interesting to measure git vs JGit performance today.

It would also be interesting to have JGit developers comment on performance after all this time.

The main complaint still stands: the report provides very few details about the incomes and expenses. Out of almost 100 slides, I only see one, titled "Financial Disclosures". And it does not contain many disclosures.

Their financial report appears to be quite opaque and closed, as opposed to the Linux project and community.

Now that SSDs are ubiquitous, hard disk drive manufacturers should up their game:

  * 5.25'' drive  which is taller (more platters) and wider (more sectors per platter)
  * Slow rotational speed to reduce consumption and vibration
  * SMR again, but label the products accordingly
  * Small (64-128GB) SSD embedded, acting as transparent cache especially for quick response to write commands.
    * Possibility to disable this caching layer with a SATA command.
