---------------------------------- The test
---------------------------------------------------
I used TortoiseSVN version 1.1.3-dev rev 2202
Computers
Processor Speed (Ghz) RAM (Mo) HD controler HD size
PC1 Celeron 1,8 256 UDMA100 20Go
PC2 Celeron 1,8 512 UDMA100 20Go
PC3 Pentium 4 2,4 512 UDMA100 40Go
PC4 Pentium 4 2,6 512 UDMA166 40Go
PC5 Pentium 4 2,6 1024 UDMA166 40Go
The HD drives are 7200 RPM with 2Mo cache.
All computers are Windows XP sp1, with Trend Micro OfficeScan.
Test repositories
Files Number Description
Rep1 4860 All files exported for a database in one folder
Rep2 3078 Only stored procedures of the previous folder
Tests method
0 Installation, configuration and checkout repository
1 Restart computer To empty cache
2 Open Explorer on checkout directory
3 select an file in it Time1 between 2 and 3
4 Change folder several times to remove files from cache
5 Go back to checkout directory
6 select an file in it Time2 between 5 and 6
Redo operations except 0 with Explorer "Max Cached Icons" to 4096 instead of
default value to 500
The results (Time1 and Time2 in seconds)
Icons Repository Time1 Time2
PC1 500 rep1 46 16
Celeron 4096 rep1 50 15
256Mo 500 rep2 17 12
4096 rep2 13 10
PC2 500 rep1 60 18
Celeron 4096 rep1 40 16
512Mo 500 rep2 15 10
4096 rep2 15 8
PC3 500 rep1 30 15
P4 4096 rep1 24 15
512Mo 500 rep2 15 8
4096 rep2 12 8
PC4 500 rep1 20 3
P4 4096 rep1 18 2
512Mo 500 rep2 15 2
4096 rep2 10 1
PC5 500 rep1 20 2
P4 4096 rep1 18 1
1Go 500 rep2 15 1
4096 rep2 8 1
Some remarks :
- PC1 and PC2 are the same computer with more RAM. I couldn't explain that
PC2 seem slower than PC1, except if RAM has got problems.
- PC4 and PC5 are the same computer.
- When I redo the operations 4 to 6 several times, time2 is quite the same
on each computers.
- I redo those tests 2 or 3 times, to be sure of the results. The difference
was of 1 or 2 seconds.
