Hi list,
Understandably, one of our customers is concerned about the impact of
enabling TSM journaling on his customer-facing performance-critical
production file-server - he asks:
>> Do you know if there is any risk of performance degradation (i.e.
slower read/write of files)
>> resulting from the interaction between the journaling daemon and the
Win32 API?
Does anyone have any comments, experiences or statistics that I can get
back to him with on this? I can understand that there might be a
performance hit, what with the extra file I/O and writes to the journal
file, but is this significant or quantifiable, and should he be
concerned?
Many thanks,
David McClelland
