# Optimizing FUSE Parameters
|
|
|
|
Properly adjusting the kernel FUSE parameters can achieve better performance in sequential writing and high-concurrency scenarios. You can refer to the following steps:
|
|
|
|
1. Obtain the Linux kernel source code.
|
|
|
|
Download the corresponding Linux kernel source code package and install the source code. The source code installation directory is `~/rpmbuild/BUILD/`.
|
|
|
|
``` bash
|
|
rpm -i kernel-3.10.0-327.28.3.el7.src.rpm 2>&1 | grep -v exist
|
|
cd ~/rpmbuild/SPECS
|
|
rpmbuild -bp --target=$(uname -m) kernel.spec
|
|
```
|
|
|
|
2. Optimize the Linux FUSE kernel module parameters.
|
|
|
|
To achieve optimal performance, you can modify the FUSE parameters `FUSE_MAX_PAGES_PER_REQ` and `FUSE_DEFAULT_MAX_BACKGROUND`. The optimized reference values are as follows:
|
|
|
|
``` C
|
|
/* fs/fuse/fuse_i.h */
|
|
#define FUSE_MAX_PAGES_PER_REQ 256
|
|
/* fs/fuse/inode.c */
|
|
#define FUSE_DEFAULT_MAX_BACKGROUND 32
|
|
```
|
|
|
|
3. Compile the corresponding version of the Linux kernel module.
|
|
|
|
``` bash
|
|
yum install kernel-devel-3.10.0-327.28.3.el7.x86_64
|
|
cd ~/rpmbuild/BUILD/kernel-3.10.0-327.28.3.el7/linux-3.10.0-327.28.3.el7.x86_64/fs/fuse
|
|
make -C /lib/modules/`uname -r`/build M=$PWD
|
|
```
|
|
|
|
4. Insert the kernel module.
|
|
|
|
``` bash
|
|
cp fuse.ko /lib/modules/`uname -r`/kernel/fs/fuse
|
|
rmmod fuse
|
|
depmod -a
|
|
modprobe fuse
|
|
``` |
