Hi Nicolas,
I responded to your email already. I’ll summarize it for everybody here.
We were not able to find any causes behind the slowdown, it doesn’t mean it is not there for certain users who may have a large mailbox or undergoing some tasks in Postbox/Thunderbird such as creating an index or a cache file. Our tests shows no major performance drops with Espionage and Postbox/Thunderbird. It is normal to see *some* drop in performance but it should not be significant. If you notice that Postbox is doing some disk operations, wait for it to complete and then see if it’ll speed up over time.
Espionage puts some folders that Postbox/Thunderbird uses in an encrypted file system and it’d be transparent to those apps, it shouldn’t slow down the overall performance of those apps in any way unless the apps are doing some inefficient disk I/O operations. This would be applied to other apps like Postbox as well.
There is not much we can do to speed things up for Postbox, the encryption protocols are built into the Mac OS X and it is the same for all apps, it should already be maximized.
If the performance loss is not acceptable after waiting a bit, I’d suggest not using Postbox with Espionage at all.
I’m sorry that I do not have a better answer for you or others who have the same slowdown with Postbox/Thunderbird.
