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

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. */
