http://bugzilla.novell.com/show_bug.cgi?id=577749#c1 --- Comment #1 from Yury Serdyuk <[email protected]> 2010-02-27 12:04:03 UTC --- I have studied the problem further and observed that indeed there is a fast growing of serialization time for float array size of >= 270 204 922 elements. Below is a corresponding protocol: bash-3.2$ mono BigSerializationTest.exe 270204920 Serialization time = 1.271595 secs. bash-3.2$ mono BigSerializationTest.exe 270204921 Serialization time = 1.236961 secs. bash-3.2$ mono BigSerializationTest.exe 270204922 Serialization time = 2.433673 secs. bash-3.2$ mono BigSerializationTest.exe 270204923 Serialization time = 2.425419 secs. bash-3.2$ mono BigSerializationTest.exe 270204924 Serialization time = 2.44311 secs. bash-3.2$ mono BigSerializationTest.exe 270204950 Serialization time = 2.846783 secs. bash-3.2$ mono BigSerializationTest.exe 270204980 Serialization time = 2.84799 secs. bash-3.2$ mono BigSerializationTest.exe 270205000 Serialization time = 2.845296 secs. bash-3.2$ mono BigSerializationTest.exe 270206000 Serialization time = 3.428312 secs. bash-3.2$ mono BigSerializationTest.exe 270210000 Serialization time = 4.644107 secs. bash-3.2$ mono BigSerializationTest.exe 270250000 Serialization time = 21.2402 secs. bash-3.2$ mono BigSerializationTest.exe 270300000 Serialization time = 40.710206 secs. bash-3.2$ mono BigSerializationTest.exe 270500000 Serialization time = 119.514284 secs. bash-3.2$ mono BigSerializationTest.exe 271000000 Serialization time = 316.298852 secs. Code for testing: using System; using System.IO; using System.Runtime.Serialization; using System.Runtime.Serialization.Formatters.Binary; public class BigSerializationTest { public static void Main ( String[] args ) { int size = Convert.ToInt32 ( args [ 0 ] ); BinaryFormatter bf = new BinaryFormatter(); MemoryStream ms = new MemoryStream(); float[] array = new float [ size ]; for ( int i = 0; i < array.Length; i++) array [ i ] = 1.0f; DateTime dt1 = DateTime.Now; bf.Serialize ( ms, array ); DateTime dt2 = DateTime.Now; Console.WriteLine ( "Serialization time = " + (dt2-dt1).TotalSeconds + " secs." ); } } Is there some possibility to resolve this problem in the nearest future? This problem is a very critical for us ... Thanks.
