Hi,

I created a small Git Repo (< 30 Files&Dirs) on a server (in the local network) with ssh access, and a clone of the repo on my local machine where eclipse/egit is running. SSH Key of my local machine is stored at this server.

Git Fetch of this repo from Command Line (mysysgit) works like a charm (< 3 seconds)
In Egit Fetch (from upstream) takes around 30 Seconds.

I executed jstack during the fetch is running and this is the output:
"Worker-4" #31 prio=5 os_prio=0 tid=0x26e9a800 nid=0x22cc runnable [0x2928f000]

Any ideas how fetch can be speeded up ?

My Configuration is:
- Windows 7 x64
- Eclipse Kepler Service Release 2 (32 bit Version)
- Java 1.7.0_45 (32 bit Version)
- Egit Latest Nightly (3.4.0.201405052355)
