Yes, I tried it and it was very effective! See below:
1.6.17 1.7.4 1.7.4-patched
NFS benchmark* 1534s 4074s 572s
Local benchmark* 365s 162s 118s
NFS svn co 29s 163s 18s
Local svn co 4s 4s 3s
Are there any downsides to this patch? It sounds like the only downside is a
delay to simultaneous read operations for the same working-copy. Those
operations are very rare for compared to the huge gains in NFS working-copy
performance.
Thanks for figuring out this patch!

Are you able to try a patch and tell us how effective it is?
