Client is downloading files very slowly for big repos. [message #1172682]

Hi,

I'm using JGit there is something strange.

When the client ( a java program with jgit that runs on jboss) tries to clone a repository with files that contains about 411mb (there are files from 1 to 100 mb) it's cloning it very slow, 8 - 12 kb's second.

When i do it with git bash, it clones very fast, it take about 2 minutes to clone the repo.

With the same repository, if there is a file about 27mb it's clone it very fast. My assumption there is some trouble when a repo contains big files or the repo is more than 100mb.

Is anything that i can do to revert this situation?

Extra Information:
JGIT Version Tested: 3.0.0.201306101825 and 3.1.0.201310021548-r
Environment: Linux Centos 6.

Try to increase jgit's window cache limit to a larger value, if there are large files to be processed
you may need to increase the stream file threshold to a value larger than the biggest file to transfer.

See parameters packedGitLimit and streamFileThreshold in class org.eclipse.jgit.storage.file.WindowCacheConfig.
