I see, a minix-like static allocation (I'm guessing this is needed
because ELKS does not yet handle overlapping segments between different
processes so it does not want to allocate a whole segment to each process
per default?).
Yes, indeed, this helped, but I had to both set
-H0xff00
and
-DBLON=3584 (reduce the compression block size)
to get rid of "no memory".
The utility still performs better than ELKS compress
but this scaling down should not be needed.
8KB compression block size works under elksemu
(about 9KB extra for the buffers compared to the 3.5KB block),
what causes this difference?
