I am wondering that another effect of the heartbleed was increased TLS overhead, that I saw many times also before April-7. Unfortunately I do not store more than 7 files worth of logs:

Especially as it looks to be highly increased after the release of the vulnerability.
How can you tell that? tor did not log those messages back in 2012 when the vulnerability was released.
I am not sure I am on right track but it does look suspicious.
What would interest me would be to know whether the period of increased TLS write overhead highlighted above involved hidden services directory connections.
