Subject: [PATCH] Do not overload I/O threads with chunk data while flush
|
|
saving
|
|
|
|
If the chunk count is high, then the memory used by the
|
|
chunks adds up and could cause problems. By flushing
|
|
every so many chunks, the server will not become
|
|
stressed for memory. It will also not increase the total
|
|
time to save, as flush saving performs a full flush at
|
|
the end anyways.
