Joshua McKenzie commented on CASSANDRA-7001:
--------------------------------------------
h5. What works:
* added +x to all .bat files so it's more convenient on cygwin
* upped heap to 2G on legacy .bat startup
* runtime determination of cassandra-env.ps1 based on similar rules as used in
cassandra on *nix
* background startup, no window popping up
* foreground startup
* pidfile watch and deletion
* -H for heap dump output
* -E for error file output
* -verbose to print startup JVM params
* new stop-server.bat to send control+c to running cassandra process for
graceful shutdown
* heap and new-gen based on available system memory
* tested on Win8 and Win7
h5. What doesn't:
* numactl. There's nothing analogous on Windows; We can look into winbase.h,
WinNT.h and native access to kernel32.dll later if we feel this is worth
pursuing (link: http://archive.msdn.microsoft.com/64plusLP)
* MALLOC_ARENA_MAX. libc specific per-thread memory arena, nothing analogous
on Windows.
h5. What wasn't tested:
* All the optional / commented out params in cassandra-env.ps1, gc etc.
Default options for the JVM on Windows should be in parity with linux w/the
current config.
h5. Performance:
* Got about a 8% bump on write, 5% on reads from the various startup changes.
Still looks to be about 20% behind OSX on reads when forcing buffered I/O
across the board on both. On the plus side, write performance tested in parity
on buffered I/O before the changes compared to OSX, 8% faster than OSX after.
> Windows launch feature parity - augment launch process using PowerShell to

> The current .bat-based launching has neither the logic nor robustness of a
> bash or PowerShell-based solution. In pursuit of making Windows a 1st-class
> citizen for C*, we need to augment the launch-process using something like
> PowerShell to get as close to feature-parity as possible with Linux.
