Subject: Optimize Horde_Imap_Client_Thread for storage
X-Git-Url: https://git.internetallee.de/?a=commitdiff_plain;h=2750429a1ccae72b9a196301d8d43697401f18ed;p=horde.git

Optimize Horde_Imap_Client_Thread for storage

Now that it may be serialized and stored in cache, optimize the internal
data structures.  New storage saves approx. 60%.
