Description
Maps saved in session files are compressed with gzip. Compression and decompression on restore are very slow compared to disk I/O. BLOSC compress and decompress would be an order of magnitude or more faster, essentially as fast as disk I/O while maintaining good compression ratios. Should be using that.
In ticket #3189 a user used ctrl-C while a map was being decompressed from a session possibly because it was taking too long.
