Currently I has a single threaded server based on boost ASIO. This works correctly most of the time. However on systems where i know that the disk's are slow. , the server grinds to a halt, when dealing with the blocking disk IO.

I could not find any examples or documentation in ASIO, in how to get round these issues. It appears that ASIO does not provide any support for async' disk IO.

So I assume this is handled by use of threads ? Are there any examples of using ASIO with threaded disk IO, since this must be very common use case ?

Is the strand functionality appropriate for handing disk IO, in an async' manner.

Any recommendations/advice on this issues would be greatly appreciated.

Hi Avi, If your server performs short read/writ frequently and data to be transfer to network depend on these operations, then multi-threading does not help a lot here. I would suggest you to recheck your I/O strategies and make sure they are optimized. e.g. buffering, cache, .. etc. If they are perfect but performance still bother you, then consider to use memory mapped file or libaio.
