squid maximum_object_size lower than allowable cvmfs chunk sizes

maximum_object_size 4096 KB

This limit is lower than the (default) allowable cvmfs chunk size, which is not optimal.

From Ryan P. Taylor:

$ grep "DEFAULT.*CHUNK_SIZE="  /usr/bin/cvmfs_server 
CVMFS_DEFAULT_MIN_CHUNK_SIZE=4194304
CVMFS_DEFAULT_AVG_CHUNK_SIZE=8388608
CVMFS_DEFAULT_MAX_CHUNK_SIZE=16777216

Reference data repositories such as bioinformatics tend to use larger chunks (32-128 megabytes), a more reasonable squid maximum_object_size might be 131072 KB instead.

Ryan P. Taylor confirms that CC data repos use CVMFS_MAX_CHUNK_SIZE=67108864

Thanks!

I bumped the limit in commit fd44045.
