<DIV>The 3.7.8 FUSE client is significantly slower than 3.7.6. Is this related to some of the fixes that were done to correct memory leaks? Is there anything that I can do to recover the performance of 3.7.6?</DIV>
<DIV> </DIV>
<DIV>My testing involved creating a "bigfile" that is 20GB. I then installed the 3.6.6 FUSE client and tested the copy of the bigfile from one gluster machine to another. The test was repeated 2x to make sure cache wasn't affect performance.</DIV>
<DIV> </DIV>
<DIV>Using Centos7.1</DIV>
<DIV>FUSE 3.6.6 took 47-seconds and 38-seconds.</DIV>
<DIV>FUSE 3.7.6 took 43-seconds and 34-seconds.</DIV>
<DIV>FUSE 3.7.8 took 205-seconds and 224-seconds</DIV>
<DIV> </DIV>
<DIV>I repeated the test on another machine that is running centos 6.7 and the results were even worse. 98-seconds for FUSE 3.6.6 versus 575-seconds for FUSE 3.7.8.</DIV>
