NetBSD/alpha has been changed to "USE_XZ_SETS=yes" as other 64 bit ports:
But at least on my DEC 3000/300 (21064 150MHz) there are several problems:
- gzip(1) gets "out of swap" during extracting base.tar.xz on sysinst.
My DEC 3000 has 64MB but it is not enough for "xz -9", as noted in
the xz(1) man page:
>> For example, decompressing a file created with xz -9 currently requires
>> 65 MiB of memory.
- Even if sysinst is configured to use swap partition, extracting
base.tar.xz and comp.tar.xz is really slow on my DEC 3000.
(~100kB/sec; similar speed to extrace gzip sets on 68040 25MHz)
- Less benefits. I guess USE_XZ_SETS was introduce to make
iso images small enough (to fit in 800MB CD size?), but current
alpha's iso with USE_XZ_SETS=no is much smaller than that.
(~300MB, and xz one is ~180MB; not sure this is reasonable though)
Just revert to set "USE_XZ_SET=no" for alpha?
Or relax the compress level of xz from -9?
