Too many requests slowing down our website

Hello,

When checking on pingdom after the activation of Mashshare, my website run slower than with another plugin and I’ve got this error message “Minimize request size :
The requests for the following URLs don’t fit in a single packet. Reducing the size of these requests could reduce latency.
data:application/octet-stream;base64,d09GRgABAA … I4tDR3JIBEhJJBBs5mFi5NHawfi/dQNL70YmBhcADHYj9AAA”

Is it possible to fix that ? ‘Cause otherwise the plugin is nice and quite lightweight.

Thanks
