Hi all, I have compiled the fusexmp.c example filesystem coming with the fuse package. As I understand it, it should be just a passthrough to the original fs underneath. I want to use that example and build upon it. Problem is, I have serious considerations regarding the performance. Using iozone, I only get ~10% write and ~20% read performance of the parent FS. I have already enabled big_writes. Is that expected behavior? I can see with iotop that there are ~10 concurrent fuse-threads writing at the same time. Perhaps that is counter productive? Also, CPU Usage is quite high. Thanks in Advance Stefan |

Stefan, You could try fusexmp_fh instead. Have a look at the read and write calls of fusexmp ... you'll see that it's open - read/write - close each time.
