Performance testing for PYBAG v 0.3.0.

For previous version PYBAG v0.2.0 full test results you can view here.

All tests given for command line interface. For GUI results is same.

First synchronization - in this time all files from origin copied to bag. this is a long synchronization.
Second synchronization - in this time scan all files in bag and origin for changes and copy only changed files. This a general mode of synchronization,  - this mode is fast.
Backup roots - this mode used for backup, and in this mode synchronization is up 2 times faster then in standart mode. But in this mode you must not manualy change files in bag.

As you can see new version PYBAG is fast!

Difference between previous and new version is great. In huge backup about 24 GB new version up 5 times faster then old for second synchronization and  more then 8 times faster in first synchronization (second synchronization - 4 minutes again 44 minutes and 47 minutes again 7 hours in first synchronization). Also in first synchronization I recomend turn off report (option -gx ) and view it only for errors or conflicts, it save you from large output for each new file.

Test 1 - Normal, ext3 (hdd) - ext3 (hdd)

Test synchronizing between same hard drive from one directory to other.

System configuration
Dell Inspiron 1525 T8300:
Core2Duo 2.4 GHz, RAM 2 GB

OS:
Linux Ubuntu 10.04
Python 2.6.5
wxPython 2.8.10.1

File systems:
origin: EXT3, HDD 5400
bag: same as origin

Items (files, folders) count: 1040 items (849 files, 188 folders, 3 symlinks).
Items size: 20 867 KBytes.
Testing result in seconds.

IF YOU LIKE PYBAG AND FOUND IT USEFUL WHEN YOU CAN DONATE TO AUTHOR SOME MONEY HERE.

If you do not want donate money then you can treat the author cap of coffee and pizza.

Donate !!!

THANK YOU.

Test 3 - Huge, ext3 (hdd) - fat32 (hdd)

This is backup test.

As view from result - first synchronization is very slow becouse need copy all files to bag (copying speed is neer then copy throw system file manager). The next synchronization is more and more faster.
