Stavo riscontrando problemi con Redis su Ubuntu: ```plaintext Your Redis network connection is performing extremely poorly. Last RTT readings were [96585, 101554, 97189, 99769, 94618], ideally these should be < 1000. Ensure Redis is running in the same AZ or dat ``` Credevo che THP fosse già disabilitato (seguendo la wiki), ma si è scoperto che era ancora abilitato 😅. Disabilitare THP ha finito per risolvere il problema sopra per me, se ricordo bene (tardo l’anno scorso). * * * Ubuntu 24.04 LTS (seguendo la wiki corrente): ```plaintext cat /sys/kernel/mm/transparent_hugepage/enabled # output: # [always] madvise never echo 'sys.kernel.mm.transparent_hugepage.enabled=never' > /etc/sysctl.d/10-huge-pages.conf cat /etc/sysctl.d/10-huge-pages.conf # output: # sys.kernel.mm.transparent_hugepage.enabled=never sudo sysctl --system # output: * Applying /usr/lib/sysctl.d/10-apparmor.conf ... * Applying /etc/sysctl.d/10-bufferbloat.conf ... * Applying /etc/sysctl.d/10-console-messages.conf ... * Applying /etc/sysctl.d/10-huge-pages.conf ... * Applying /etc/sysctl.d/10-ipv6-privacy.conf ... * Applying /etc/sysctl.d/10-kernel-hardening.conf ... * Applying /etc/sysctl.d/10-magic-sysrq.conf ... * Applying /etc/sysctl.d/10-map-count.conf ... * Applying /etc/sysctl.d/10-network-security.conf ... * Applying /etc/sysctl.d/10-ptrace.conf ... * Applying /etc/sysctl.d/10-zeropage.conf ... * Applying /usr/lib/sysctl.d/50-pid-max.conf ... * Applying /etc/sysctl.d/99-cloudimg-ipv6.conf ... * Applying /usr/lib/sysctl.d/99-protect-links.conf ... * Applying /etc/sysctl.d/99-sysctl.conf ... * Applying /etc/sysctl.conf ... kernel.apparmor_restrict_unprivileged_userns = 1 net.core.default_qdisc = fq_codel kernel.printk = 4 4 1 7 net.ipv6.conf.all.use_tempaddr = 2 net.ipv6.conf.default.use_tempaddr = 2 kernel.kptr_restrict = 1 kernel.sysrq = 176 vm.max_map_count = 1048576 net.ipv4.conf.default.rp_filter = 2 net.ipv4.conf.all.rp_filter = 2 kernel.yama.ptrace_scope = 1 vm.mmap_min_addr = 65536 kernel.pid_max = 4194304 net.ipv6.conf.all.use_tempaddr = 0 net.ipv6.conf.default.use_tempaddr = 0 fs.protected_fifos = 1 fs.protected_hardlinks = 1 fs.protected_regular = 2 fs.protected_symlinks = 1 cat /sys/kernel/mm/transparent_hugepage/enabled # output: # [always] madvise never ``` * * * AlmaLinux 10 (seguendo la wiki corrente): ```plaintext cat /sys/kernel/mm/transparent_hugepage/enabled # output: # [always] madvise never echo 'sys.kernel.mm.transparent_hugepage.enabled=never' > /etc/sysctl.d/10-huge-pages.conf cat /etc/sysctl.d/10-huge-pages.conf # output: # sys.kernel.mm.transparent_hugepage.enabled=never sudo sysctl --system # output: * Applying /usr/lib/sysctl.d/10-default-yama-scope.conf ... * Applying /etc/sysctl.d/10-huge-pages.conf ... * Applying /usr/lib/sysctl.d/10-map-count.conf ... * Applying /usr/lib/sysctl.d/50-coredump.conf ... * Applying /usr/lib/sysctl.d/50-default.conf ... * Applying /usr/lib/sysctl.d/50-libkcapi-optmem_max.conf ... * Applying /usr/lib/sysctl.d/50-pid-max.conf ... * Applying /usr/lib/sysctl.d/50-redhat.conf ... * Applying /etc/sysctl.d/99-sysctl.conf ... * Applying /etc/sysctl.conf ... kernel.yama.ptrace_scope = 0 vm.max_map_count = 1048576 kernel.core_pattern = |/usr/lib/systemd/systemd-coredump %P %u %g %s %t %c %h kernel.core_pipe_limit = 16 fs.suid_dumpable = 2 kernel.sysrq = 16 kernel.core_uses_pid = 1 net.ipv4.conf.default.rp_filter = 2 net.ipv4.conf.eth0.rp_filter = 2 net.ipv4.conf.eth1.rp_filter = 2 net.ipv4.conf.lo.rp_filter = 2 net.ipv4.conf.default.accept_source_route = 0 net.ipv4.conf.eth0.accept_source_route = 0 net.ipv4.conf.eth1.accept_source_route = 0 net.ipv4.conf.lo.accept_source_route = 0 net.ipv4.conf.default.promote_secondaries = 1 net.ipv4.conf.eth0.promote_secondaries = 1 net.ipv4.conf.eth1.promote_secondaries = 1 net.ipv4.conf.lo.promote_secondaries = 1 net.ipv4.ping_group_range = 0 2147483647 net.core.default_qdisc = fq_codel fs.protected_hardlinks = 1 fs.protected_symlinks = 1 fs.protected_regular = 1 fs.protected_fifos = 1 net.core.optmem_max = 81920 kernel.pid_max = 4194304 kernel.kptr_restrict = 1 net.ipv4.conf.default.rp_filter = 1 net.ipv4.conf.eth0.rp_filter = 1 net.ipv4.conf.eth1.rp_filter = 1 net.ipv4.conf.lo.rp_filter = 1 cat /sys/kernel/mm/transparent_hugepage/enabled # output: # [always] madvise never ``` * * * Forse questo sarebbe adatto per la wiki?
