2.28. Why is extracting files via tar so slow?
{AJ} Extracting of tar archives might be quite slow since tar has to look up
userid and groupids and doesn't cache negative results. If you have nis or
nisplus in your /etc/nsswitch.conf for the passwd and/or group database,
each file extractions needs a network connection. There are two possible
solutions:
- do you really need NIS/NIS+ (some Linux distributions add by default
nis/nisplus even if it's not needed)? If not, just remove the entries.
- if you need NIS/NIS+, use the Name Service Cache Daemon nscd that comes
with glibc 2.1.

/* This is a gross hack to get borken programs running.
/* This is a gross hack to get broken programs running.
ISO C provides no mean to find out how many bytes the wide
character representation really uses. But it defines MB_CUR_LEN to
return the information for the multi-byte character representation.
Many programmers don't know the difference between the two and
thing this means the same. But assuming all characters have a size
think this means the same. But assuming all characters have a size
of MB_CUR_LEN after they have been processed by `mbrtowc' is wrong.
Instead the maximal number of character used for the conversion is
MB_CURLEN.
Instead the maximum number of characters used for the conversion is
MB_CUR_LEN.
It is known that some Motif applications have this problem. To
cure this one has to make sure the glibc uses the function in this
file instead of the one in locale/mb_cur_max.c. This can either be
done by linking with this file or by using the LD_PRELOAD feature
of the dynamic linker. */
