1) Buffer Pool size now defaults to 1GB and a minimum of 64MB
2) Log files are 3 by default and each 128MB in size
3) Removed innodb-file-io-threads config variable since no longer used
4) Set read io and write io threads to 8 by default for better default performance
5) Set log buffer size to 16 MB by default and minimum to 2MB
6) Set additional memory buffer pool to 8 MB and minimum to 2MB
7) Set max dirty percent to 75% and decreased to 99% to never allow a completely dirty buffer pool
8) Increased io capacity to 200 for a good default
Replaced abs_top_srcdir with top_srcdir, not sure it's an
improvement but at least it's known that abs_top_srcdir
in cases have a problem and this is a more common variable
to use for the same purpose.
for files in tar command as part of make of a source distribution.
Only 99 characters are supported. Abbreviated performance version
by pv thus. Should be ok since shorter than ndb, and if MySQL Cluster
Carrier Grade Edition has thus 1 character longer version names.
platforms and emphasize the fact that gcc is the default
compiler on all platforms.
Make it possible to say --compiler=SunStudio instead of
--compiler=forte
Fix a bug that lost an important flag for C++ builds.
for those cases when gcc, cc-5.0, icpc or icc isn't in the path.
Fixed handling of 32 and 64 bits.
Downgraded Solaris builds on Forte to use -xO2 rather than -xO3.
Made it possible to build 64-bits on Mac OS X
Fixed some bugs in setting CC, CXX, ASFLAGS, LDFLAGS
Fixed bugs relating to use of SunStudio/Forte in check-cpu
Reorganized code a bit
Removed the use of --with-fast-mutexes since they aren't really
fast, rather slow.
Added -static-libgcc when using gcc
Added optimising compilation flags on BSD
Added use of curses library on Solaris
Removed the use of MY_ATOMIC_MODE_RWLOCKS which removed use of
atomic instructions
Added support for Forte on Solaris/x86
parameter innodb_thread_concurrency_timer_based is used to
get this new feature (it is set by default). The new feature
is only available on platforms where atomic instructions are
available.
Change defaults, now large page support is default if supported
Introduced super-large-pages support for Solaris to use 256 MByte
page size rather than 4 MByte.
