我在Mac上在终端中,您将如何计算出以下每个值？
>字大小(64位与32位)
> L1 / L2缓存大小
>确定使用了多少内存(如df,但是用于RAM)
谢谢！我知道你可以在Activity Monitor,System Profiler等中找到这些内容,但是我正在提高我对终端和UNIX的了解.
System Profiler是围绕/usr/sbin / system_profiler的GUI包装器.
mress:10008 Z$system_profiler -listDataTypes Available Datatypes: SPHardwareDataType SPNetworkDataType SPSoftwareDataType SPParallelATADataType SPAudioDataType SPBluetoothDataType SPCardReaderDataType SPDiagnosticsDataType SPDiscBurningDataType SPEthernetDataType SPFibreChannelDataType SPFireWireDataType SPDisplaysDataType SPHardwareRAIDDataType SPMemoryDataType SPPCIDataType SPParallelSCSIDataType SPPowerDataType SPPrintersDataType SPSASDataType SPSerialATADataType SPUSBDataType SPAirPortDataType SPFirewallDataType SPNetworkLocationDataType SPModemDataType SPNetworkVolumeDataType SPWWANDataType SPApplicationsDataType SPDeveloperToolsDataType SPExtensionsDataType SPFontsDataType SPFrameworksDataType SPLogsDataType SPManagedClientDataType SPPrefPaneDataType SPStartupItemDataType SPSyncServicesDataType SPUniversalAccessDataType mress:10009 Z$system_profiler SPHardwareDataType Hardware: Hardware Overview: Model Name: iMac Model Identifier: iMac10,1 Processor Name: Intel Core 2 Duo Processor Speed: 3.33 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 6 MB Memory: 16 GB Bus Speed: 1.33 GHz Boot ROM Version: IM101.00CC.B00 SMC Version (system): 1.52f9 Serial Number (system): QP0241DXB9S Hardware UUID: 01C6B9E9-B0CB-5249-8AC7-069A3E44A188
您还可以从/usr/sbin / sysctl获取一些有用的信息(尝试sysctl -a).
mress:10014 Z$sudo sysctl -a | grep cache Password: hw.cachelinesize = 64 hw.l1icachesize = 32768 hw.l1dcachesize = 32768 hw.l2cachesize = 6291456 kern.flush_cache_on_write: 0 vfs.generic.nfs.client.access_cache_timeout: 60 vfs.generic.nfs.server.reqcache_size: 64 net.inet.ip.rtmaxcache: 128 net.inet6.ip6.rtmaxcache: 128 hw.cacheconfig: 2 1 2 0 0 0 0 0 0 0 hw.cachesize: 17179869184 32768 6291456 0 0 0 0 0 0 0 hw.cachelinesize: 64 hw.l1icachesize: 32768 hw.l1dcachesize: 32768 hw.l2cachesize: 6291456 machdep.cpu.cache.linesize: 64 machdep.cpu.cache.L2_associativity: 8 machdep.cpu.cache.size: 6144
