Hi,
I have set up the Grid with default configuration ( N= 10 k=3)
I have uploaded a same 4MB file 10 times and i measured the time to
upload a file using python script(time taken between start of upload and
getting of Cap string).
Following are the times for uploading a same 4MB file 10 times.
upload of a same 4MB file 10 times
------------------------------------------------
First time : * 12.91693 sec*
Second time : 1.475234 sec
Third time : 1.420883 sec
1.410683 sec
1.371741 sec
1.424991 sec
1.402836 sec
1.423402 sec
1.414753 sec
Tenth time: 1.430242 sec
For the first time, upload has taken 12.91693 sec and for the remaining
uploads, it has taken around 1 sec.
Can any one tell why is there a big difference compared to the initial
upload time and remaining upload times?
Is it because of key creation for the initial file upload? and I have not
set up any Tahoe BackupDB.
