Hi,
Here are the results of comparison of kernel 2.5.55 and 2.5.54
on TIObench. key findings are listed in the table. Values in the
table indicate approximate percentage change with respect to previous result.
Please see the mail in full window to see the formatted results.

-------------------------------------------------------------
test 2.5.55 (as compared to
2.5.54) APPROXIMATE % change
-------------------------------------------------------------
rate (megabytes per second) no much change
CPU % utilization 15% decrease
Average Latency 15% decrease
Maximum latency less than 10 % increase
CPU efficiency 10% increase
-------------------------------------------------------------

No size specified, using 252 MB

Unit information
================
File size = megabytes
Blk Size = bytes
Rate = megabytes per second
CPU% = percentage of CPU used during the test
Latency = milliseconds
Lat% = percent of requests that took longer than X seconds
CPU Eff = Rate divided by CPU% - throughput per cpu load
