Slow history load

[v_2e]

Hello!
  I have noticed that Coccinella tends to open the history veeeeeeeery slowly when the history file contains ~100 000 lines. It opens such history files in about a minute I guess. The smaller history files are also loaded not very fast.
  Moreover, I have also noticed that the chat window itself is loaded very slowly when the history of the corresponding contact is long enough. This is very inconvenient since it often happens that somebody (whith whom I have a long chat history) sends me a chat message (a new chat) while I'm having a conversation with someone else. It makes Coccinella become irresponsive for about 10 seconds until the new chat is fully opened and the history tail is loaded in it.

  Is there any way to optimize the histoy loading process to reduce these irresponsive times?

  Thank you.
