そして，Pagesを使用して書類に追記を始めたらプチフリーズが頻発しました。継続時間は3〜5秒程度で，一番ひどいときの16秒に比べればましです．<\/p>\n\n\n\n

Black Magic Design Disk Speed Testで測定したら，速度の大幅低下が確認できました．<\/p>\n\n\n

予想通り，Mac miniをしばらく使用していて，特にPagesを開いている時間が長いと~\/LibraryMetadata\/CoreSpotlight<\/code>の内容量が増大します．<\/p>\n\n\n\n

50GBを超えたあたりで，プチフリーズが発生し，その状況下でSSDのアクセス速度を測ると大幅な低下が確認できます．<\/p>\n\n\n\n

ここで，~\/LibraryMetadata\/CoreSpotlight<\/code>の内容を削除して再起動すればプチフリーズは解消し，SSDのアクセス速度も回復するはずです．<\/p>\n\n\n\n

再起動後<\/h3>\n\n\n\n

たしかに，SSDのアクセス速度は回復しました．プチフリーズも今のところないです．<\/p>\n\n\n
