iPhone 4S - I/O Performance

iPhone 4S - I/O Performance ?

I'm curious about if I/O performance of iPhone 4S has enhanced or the same...

Could someone who has an iPhone 4S try to iBenchmark! and share the scores ?

itunes.apple.com/sk/app/ibenchmark!/id423223184?mt=8

iBenchmark! is free btw...

My scores for iPhone 4 w/ iOS [No JB] are here below:

Memory Allocation: 200.3 per sec.
Memory Copy: 863.1 per sec.
Disk Write: 20.5 MB/s
Disk Read: 101.2 MB/s

There is very little noticeable difference in performance between the 4 and the 4s for me.

Memory Allocation: 483.3 per sec.
Memory Copy: 479.2 per sec.
Disk Write: 30.0 MB/s
Disk Read: 106.9 MB/s

Thx rstark18 - i believe the scores you posted are very substantial.

I see mem alloc more than twice of iPhone 4 !

I don't know why your mem copy score is lower but i guess it's because some task in the background - although i didn't mention in my post i killed all task in the bg before executing the benchmark.

Disk write 30 MB/s is also spectacular too !

I've had similar tests with some friends Galaxy S II [GSM Europe] and Galaxy Tab [Original P 1000] and their writes are below 10 MB/s and reads are under 30 MB/s - of course for their internal storage. SD Cards are even are lower though maybe a Class 10 card may enhance the performance.

I don't think any other smartphone can beat iPhone 4/4S atm for the I/O performance.

IOS file system possibly effects this positively too...

Ok killed all BG tasks:

Memory Allocation: 496.3 per sec.
Memory Copy: 522.1 per sec.
Disk Write: 30.9 MB/s
Disk Read: 106.6 MB/s

Damn that's quick.

Hmm interesting...

Apparently write speed is 31MB/s to the flash memory - which is really superb.

Mem alloc again is great with the new A5 chip.

But honestly speaking mem copy ops puzzled me.

Though may i ask if those are the first run scores ? What happens after you run three times in row ?

For big games and apps this means that iPhone 4S can load upto %50 faster theoretically.

Very nice !
