data speed estimate

[julie_777]

I can see that Symbian Wlan speed is very low compared to android or Ios , any idea whyit is too slow ? is it dude to some s60 issues?

That is of course meaningless, those are all operating systems you are listing, while WLAN speed is mainly determined by hardware. So the actual device model matters (like newer models support 802.11b/g/n, but 3 years ago it was just 802.11b/g, you could check in the specification pages). It may also matter how speed is measured.

So Os has no impact on Wlan Speed?

Since you mention S60, those devices support 802.11b/g. That can receive 2-3 megabytes at most in a second. The OS has nothing to do with that, and this amount of data is effortlessly manageable for Symbian running on a 3-400 MHz CPU.

Howver, Symbian is/was in the past, at least, notoriously slow (inefficient) in handling WLAN traffic, so it is not just about WLAN hardware/drivers, but how the OS handles that (e.g., memory management).

Inefficiency is very probable, as Symbian loves copying descriptors between processes. But I can not recall WLAN being very slow compared to other 802.11b/g devices (N95 vs. iPAQ something vs. Nexus One). In my particular development case bad things started when writing the received data to mass storage drive in small chunks (~1-2 kilobytes). Allocating a 20k buffer for collecting pieces (it was a BitTorrent-like protocol) helped a lot.
