【特性描述】 xfs支持日志grant track byte, 替换原先使用的基于lsn跟踪的方式, 减少xfs日志各个环节反复拆装lsn, 减少在日志在高并发场景下的cpu消耗, 提升xfs高并发场景下的性能. 【特性收益】 提升xfs日志并发时cpu消耗, 如在128核鲲鹏920服务器上, 64容器内基于xfs文件系统并发跑will-it-scale fallocate2测试, 相比优化前性能提升1~2倍. 硬件环境: kunpeng920 128核 / HWE52P431T6M005N nvme盘 测试命令:/will-it-scale/fallocate2_processes -n -t 1 -s 10 | grant方式 | track lsn | track byte | |---|---|---| | 64容器结果 | 6630.09375 | 15567.42188 | 【适用场景】 适用所有存在并发使用xfs文件系统的场景 【交付个人/团队】 NA
