For the broader BitTorrent protocol options (connections, rate limits, encryption), see [BitTorrent Configuration](https://deepwiki.com/YouROK/TorrServer/5.2-bittorrent-configuration). For the cache visualization in the UI, see [Torrent Details and Cache Visualization](https://deepwiki.com/YouROK/TorrServer/4.5-torrent-details-and-cache-visualization).

This is the maximum amount of torrent data held in memory or on disk at any given time across all pieces. **Validation in `SetBTSets()`:** - If `CacheSize == 0`, it is set to `64 * 1024 * 1024` (64 MB) [server/settings/btsets.go103-105](https://github.com/YouROK/TorrServer/blob/d266990f/server/settings/btsets.go#L103-L105) **Initialization in `Cache.Init()`:** - If the capacity passed to `NewCache()` is zero (which happens when `CacheSize` is 0 at the time `NewCache` is called), the cache falls back to `info.PieceLength * 4` [server/torr/storage/torrstor/cache.go57-59](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/cache.go#L57-L59) - In `Cache.AdjustRA()`, when `settings.BTsets.CacheSize == 0`, the capacity is dynamically updated to `readahead * 3` on each progress tick [server/torr/storage/torrstor/cache.go126-129](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/cache.go#L126-L129) Currently the readahead value passed by `Torrent.updateRA()` is a fixed 16 MB [server/torr/torrent.go224-226](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/torrent.go#L224-L226) **Effect on eviction:** The `cleanPieces()` function compares `c.filled` against `c.capacity`. When `filled > capacity`, it evicts the oldest-accessed pieces outside the active reader ranges until filled returns to capacity [server/torr/storage/torrstor/cache.go187-212](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/cache.go#L187-L212) * * * ## Storage Backend: RAM vs Disk `UseDisk` and `TorrentsSavePath` together control whether pieces are stored in process memory (`MemPiece`) or in files on disk (`DiskPiece`). **Diagram: Piece Backend Selection** ``` false true NewPiece(id, cache) (piece.go:24) settings.BTsets.UseDisk? NewMemPiece(p) buffer []byte in heap NewDiskPiece(p) file at TorrentsSavePath/hash/pieceId ``` Sources: [server/torr/storage/torrstor/piece.go24-36](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/piece.go#L24-L36) [server/torr/storage/torrstor/mempiece.go16-18](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/mempiece.go#L16-L18) [server/torr/storage/torrstor/diskpiece.go23-32](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/diskpiece.go#L23-L32) ### MemPiece `MemPiece` stores each piece as a `[]byte` slice allocated on first write [server/torr/storage/torrstor/mempiece.go20-35](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/mempiece.go#L20-L35) Releasing a `MemPiece` nils the slice, freeing it for garbage collection. This is the default and recommended mode for most deployments. On flash-based storage (e.g., Android, NAS with eMMC), RAM is preferred to avoid wear. ### DiskPiece `DiskPiece` stores each piece as a file at: ``` // ``` The path is constructed in `NewDiskPiece()` [server/torr/storage/torrstor/diskpiece.go23-32](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/diskpiece.go#L23-L32) If the file already exists at startup (e.g., from a previous session), size and completion state are read from file metadata. On every `ReadAt()` and `WriteAt()`, the file is opened and closed. Releasing a `DiskPiece` calls `os.Remove()` on the piece file [server/torr/storage/torrstor/diskpiece.go77-85](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/diskpiece.go#L77-L85) ### TorrentsSavePath and .tsc Auto-Detection When `SetBTSets()` is called with `UseDisk = true` and a non-empty `TorrentsSavePath`, it asynchronously walks the directory tree looking for a subdirectory named `.tsc` (case-insensitive). If found, `TorrentsSavePath` is updated to that subdirectory's absolute path [server/settings/btsets.go132-146](https://github.com/YouROK/TorrServer/blob/d266990f/server/settings/btsets.go#L132-L146) This allows placing a `.tsc` folder inside a larger storage root (e.g., a network share) to direct cache files to a specific subfolder without changing the top-level path configuration. If `TorrentsSavePath` is empty, `UseDisk` is forced to `false` [server/settings/btsets.go127-129](https://github.com/YouROK/TorrServer/blob/d266990f/server/settings/btsets.go#L127-L129) `Cache.Init()` creates the per-torrent directory (`TorrentsSavePath/`) if it does not exist [server/torr/storage/torrstor/cache.go65-71](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/cache.go#L65-L71) * * * ## RemoveCacheOnDrop This flag controls whether disk cache files are deleted when a torrent is **dropped** (disconnected from the BitTorrent client but retained in the database). **Behavior table:** | Action | `RemoveCacheOnDrop = true` | `RemoveCacheOnDrop = false` | | --- | --- | --- | | Drop torrent (`DropTorrent`) | Cache files deleted | Cache files kept | | Delete torrent (`RemTorrent`) | Cache files always deleted | Cache files always deleted | The drop path goes through `Cache.Close()` [server/torr/storage/torrstor/cache.go89-118](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/cache.go#L89-L118) When `RemoveCacheOnDrop` is true, it iterates all pieces, calls `os.Remove()` on each `dPiece.name`, then removes the hash directory. The delete path in `RemTorrent()` unconditionally removes the cache directory when `UseDisk` is true, regardless of `RemoveCacheOnDrop` [server/torr/apihelper.go161-181](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/apihelper.go#L161-L181) This flag has no effect when `UseDisk = false` since `MemPiece` data is released automatically when the `Cache` is closed. * * * ## ReaderReadAHead `ReaderReadAHead` is an integer percentage (5–100, recommended 95) that controls how the available cache window is split between data behind and ahead of the current read position. **Validation:** Values below 5 are clamped to 5; values above 100 are clamped to 100 [server/settings/btsets.go113-118](https://github.com/YouROK/TorrServer/blob/d266990f/server/settings/btsets.go#L113-L118) **Window calculation in `Reader.getOffsetRange()`** [server/torr/storage/torrstor/reader.go143-161](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/reader.go#L143-L161): ``` prc = ReaderReadAHead (e.g. 95) share = Cache.capacity / readers (capacity split across active readers) beginOffset = r.offset - share * (100 - prc) / 100 endOffset = r.offset + share * prc / 100 ``` **Diagram: ReadAhead Window at 95%** ``` ``` Pieces outside this `[beginOffset, endOffset]` range that are not at the start or end of the file (`isIdInFileBE`) are candidates for eviction in `getRemPieces()` [server/torr/storage/torrstor/cache.go214-256](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/cache.go#L214-L256) The piece priority assignment in `setLoadPriority()` also uses this range to set anacrolix torrent piece priorities (`PiecePriorityNow`, `PiecePriorityNext`, `PiecePriorityReadahead`, `PiecePriorityHigh`, `PiecePriorityNormal`) relative to the reader head position [server/torr/storage/torrstor/cache.go258-290](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/cache.go#L258-L290) Sources: [server/torr/storage/torrstor/reader.go143-161](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/reader.go#L143-L161) [server/torr/storage/torrstor/cache.go214-256](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/cache.go#L214-L256) [server/torr/storage/torrstor/cache.go258-290](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/storage/torrstor/cache.go#L258-L290) * * * ## PreloadCache `PreloadCache` is a percentage (0–100, default 50) of `CacheSize` that defines how many bytes to prefetch before playback begins. **Computed preload size in `Preload()`** [server/torr/apihelper.go266-277](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/apihelper.go#L266-L277): ``` size = CacheSize * PreloadCache / 100 ``` If `size <= 0`, preloading is skipped entirely. If `size > CacheSize`, it is clamped to `CacheSize`. **Example at defaults (CacheSize = 64 MB, PreloadCache = 50):** ``` size = 64 MB * 50 / 100 = 32 MB ``` The UI notes that if the computed size is ≤ 32 MB, the preload buffer slider is effectively at its minimum useful value [web/src/locales/en/translation.json31](https://github.com/YouROK/TorrServer/blob/d266990f/web/src/locales/en/translation.json#L31-L31) **Preload mechanics in `Torrent.Preload()`** [server/torr/preload.go20-273](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/preload.go#L20-L273): - Two readers are created: one reads from file start, one from file end (last `startend` bytes, where `startend = max(pieceLength, 8 MB)`). - Both run concurrently until `size` bytes are fetched or the torrent state changes from `TorrentPreload`. `PreloadCache = 0` effectively disables preloading (any `stream?preload` API call becomes a no-op).

In `Torrent.Preload()`, `readerStart.SetResponsive()` and `readerEnd.SetResponsive()` are called unconditionally during the preload phase [server/torr/preload.go141-143](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/preload.go#L141-L143) [server/torr/preload.go182-184](https://github.com/YouROK/TorrServer/blob/d266990f/server/torr/preload.go#L182-L184) `ResponsiveMode` is a global preference exposed via the `BTSets` struct [server/settings/btsets.go77](https://github.com/YouROK/TorrServer/blob/d266990f/server/settings/btsets.go#L77-L77) When disabled, the reader waits for the complete piece hash check before forwarding data. This increases latency but can avoid serving corrupt data to players.
