Jacksum supports 489 algorithms, including the most common cryptographic and non-cryptographic hash functions. Jacksum also supports the "Rocksoft (tm) Model CRC Algorithm" to customize your CRC.
Jacksum can perform a verification of hashes against a set of known hashes, and it can detect matching, non-matching, missing, and new files.
Jacksum takes advantage of modern multi-processor/multi-core environments, and saves time by hashing multiple files in parallel, and by computing hashes with multiple algorithms in parallel.
Output can occur in predefined standard formats (BSD-, GNU/Linux-, or Solaris style, SFV or FCIV) or in a user-defined format which is highly customizable, including many encodings for representing hash values, including binary, decimal, octal, hexadecimal with lowercase or uppercase letters, Base16, Base32 with and without padding, Base32hex with and without padding, Base64 with and without padding, Base64url with and without padding, BubbleBabble, and z-base-32.
Input data can come from files, standard input stream (stdin), or provided directly by command line arguments.
Jacksum supports many charsets for reading and writing files properly, and it comes with full support for all common Unicode aware charsets such as UTF-8, UTF-16, UTF-16BE, UTF-16LE, UTF-32, UTF-32BE, UTF-32LE, GB18030, etc.
With Jacksum you can also find the algorithm used to calculate a checksum, CRC, hash or find files that match a given hash value.

Based on our record, fio seems to be a lot more popular than Jacksum. While we know about 14 links to fio, we've tracked only 1 mention of Jacksum. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.

Assuming two systems use flash storage, network bandwidth is identical and it is configured the same way, there should be an issue within the PC, either system or storage drive. Check the system logs for errors and warning events related to data transfer from/to NAS. Try to benchmark the PCs' disks using fio to confirm they have similar performance. https://github.com/axboe/fio. Source: 12 months ago
Not specifically addressing your question, but when you get to the point of wanting to start doing some experiments you may find that 'fio' [1] is very handy. [1] https://github.com/axboe/fio. - Source: Hacker News / about 1 year ago
The dd is not a good benchmarking tool, you should use something like fio and probably tune it to use the ioengine most similar to your use case (eg. a database server will probably use some async IO interface). In your first example (with bs=1G) probably something (the guest OS, the qemu/kvm or the host OS) have split into smaller chunks anyway. Source: over 1 year ago
All linux tests are run with fio 3.32 (github) with future commit 03900b0bf8af625bb43b10f0627b3c5947c3ff79 manually applied. Source: over 1 year ago
Agree, I used flex/yacc to add an arithmetic expression evaluator to fio a few years back to allow simple math with some units in fio's job files, and for stuff like that, they're fine, but I wouldn't want to use them for a real language, the error handling is kind of a nightmare.
