In Windows platform, if there are more than one replicas writing to disk, the segment log files will not be consistent in disk and then consumer reading performance will be dropped down greatly. This fix allocates more disk spaces when rolling a new segment, and then it will improve the consumer reading performance in NTFS file system. This patch doesn't affect file allocation of other filesystems, for it only adds statements like 'if(Os.iswindow)' or adds methods used on Windows. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
