Very slow to apply patch on Android device

[fzyzcjy]

Hi I try to use the applier on an Android device. However, for about 15MB old apk and 2MB patch file, it takes ~8s to complete. It is normal? (Seems to be very slow...) Thanks!

Your newApk should used zlib and set compressLevel 9, so recompress it very slow when patch.
You can recompress the newApk by compressLevel 6 befor release, patch speed meybe to 2x (takes ~4s?)

@sisong Sounds reasonable, thanks!

optimize speed, recompress apk can used muti-thread on android device, but need edit source code.
