3.50m compression 12MB/sWhile waiting for the M compatible version of TWRP to come out, I noticed TWRP backups using compression have tripled or quadrupled in time on the N9 since running M vs. L. I'm unencrypted and a backup with compression takes 35-40 minutes. (2.9 GB), while uncompressed takes about 10 minutes (5.76 GB). Looking in the recovery log file the only thing I found unusual was the line TW_INCLUDE_Crypto :=true (which I am not). By contrast the N6 takes about 7 minutes to backup a similar size image compressed. Average backup rate for files systems is 2 MB/sec for the N9 vs. 12 MB/sec on the N6. I don't know why this is but I thought it was important to note, and I haven't read of anyone else testing backup times. Next time you run a compressed backup report back and let's compare times.
1.44m uncompressed 31MB/s
