[Boost-users] Increase iostream zlib filter buffer size

I am using boost serialization(binary_oarchive) with iostream zlib filter. It is working fine but its too slow(takes 10hrs). After debugging I could see the buffer size as 4KB. My data is about 600MB. How can I increase the size of buffer to say 10MB. I tried following options:- 1. passing buffer size in zlib_compressor. 2. Redefining BOOST_IOSTREAMS_DEFAULT_DEVICE_BUFFER_SIZE to 10485760 But none of above seems to work. Please guide. -- View this message in context: http://boost.2283326.n4.nabble.com/Increase-iostream-zlib-filter-buffer-size... Sent from the Boost - Users mailing list archive at Nabble.com.
