The topic of subversion client performance on Windows versus Linux was
discussed (to death) not long ago. Please see thread:

http://subversion.ti​gris.org/ds/viewMess​age.do?dsForumId=106​5&dsMessageId=98​1830

As to the effect of a (very badly configured) virus scanner as a
factor, please note something I contributed at that time:

http://subversion.ti​gris.org/ds/viewMess​age.do?dsForumId=106​5&dsMessageId=98​2805

The brain-dead McAffee configuration responsible for the performance
gap described in the above message is not something under the user's
control. It is imposed from without by the employer out of fear (of
viruses).
