- Available RAM: ${AVAILABLE_RAM_GB}GB
|
||||
- Free Disk: ${DISK_FREE_GB}GB
|
||||
|
||||
Optimization Settings:
|

- Sync Jobs: $SYNC_JOBS
|
||||
- Java Heap: ${JAVA_HEAP_SIZE:-N/A}GB
|
||||
- ccache Size: 50GB
|
||||
- tmpfs Size: ${TMPFS_SIZE:-0}GB
|
||||
|
||||
Applied Optimizations:
|
||||
✓ CPU governor set to performance
|
||||
✓ Memory management tuned
|
||||
✓ I/O scheduler optimized
|
||||
✓ Network buffers increased
|
||||
✓ Compiler flags optimized
|
||||
✓ Java environment tuned
|
||||
✓ ccache configured
|
