---------------------------------------
2.0.0-M4 is also affected by this bug.
> CumulativeProtocolDecoder doDecode performance problem
> ------------------------------------------------------
>
> Key: DIRMINA-663
> URL: https://issues.apache.org/jira/browse/DIRMINA-663
> Project: MINA
> Issue Type: Bug
> Components: Filter
> Affects Versions: 2.0.0-RC1
> Environment: JDK 1.6.0_12 32-bit, Windows Vista 64-bit, MINA
> 2.0.0-RC1 (up to current date trunk).
> Reporter: Serge Baranov
> Priority: Critical
>
> To reproduce get the mina_test_2.0.zip from DIRMINA-609.
> It seems to be working even worse with the current trunk version, it takes ~5
> seconds between messages and then times out after the first message, if wait
> is increased to 10 seconds, it times out after the second message:
> time = 03:49:36.320
> remaining = 1024
> limit = 1024
> capacity = 2048
> time = 03:49:41.619
> remaining = 2048
> limit = 2048
> capacity = 2097156
> java.lang.AssertionError: No message received
> The issue differs from DIRMINA-609 as it affects not only large messages, but
> any message that doesn't fit into buffer (when doDecode returns false) and
> also all the subsequent messages (when doDecode returns true).
> It's a serious issue making CumulativeProtocolDecoder completely useless.
