Publishing small artifacts takes a lot of time

Hi

During analyzing time spent by our builds we found strange thing.
Publishing 31 files each near 10Kb in average, spent 3 minutes.
Here is list of file sizes.
4.43Kb, 18.70Kb, 79.26Kb, 459b, 10.10Kb, 2.15Kb, 1.76Kb, 769b, 1.4Kb, 1.31Kb, 1.6Kb, 1.6Kb, 2.56Kb, 313b, 4.88Kb, 5.48Kb, 1.12Kb, 1.18Kb, 165b, 129b, 1.12Kb, 2.95Kb, 165b, 6.5Kb, 4.48Kb, 1.11Kb, 817b, 165b, 105b, 1,019b, 2.54Kb

Here is search rules
\[21:32:52\]: Publishing artifacts (3m:25s)
\[21:32:52\]: \[Publishing artifacts\] Paths to publish: \[Folder1/Folder2/Folder3/. => /, , Folder1/Folder2/Folder3/Folder4/. => /, teamcity-info.xml\]
\[21:32:52\]: \[Publishing artifacts\] Publishing artifacts 'Folder1/Folder2l/Folder3/.' to /
\[21:35:44\]: \[Publishing artifacts\] Publishing artifacts 'Folder1/Folder2/Folder3/Folder4/.' to /
\[21:36:19\]: Build finished

Is it normal, or it can be fixed by some build setting?
