libblosc1 1.21.1+ds2-2 (armhf binary) in ubuntu jammy

 Blosc is a high performance compressor optimized for binary data. It has been
 designed to transmit data to the processor cache faster than the traditional,
 non-compressed, direct memory fetch approach via a memcpy() OS call. Blosc is
 meant not only to reduce the size of large datasets on-disk or in-memory, but
 also to accelerate memory-bound computations.
 .
 It uses the blocking technique to reduce activity on the memory bus as much
 as possible. In short, this technique works by dividing datasets in blocks
 that are small enough to fit in caches of modern processors and perform
 compression / decompression there. It also leverages, if available, SIMD
 instructions (SSE2) and multi-threading capabilities of CPUs, in order to
 accelerate the compression / decompression process to a maximum.
